FOREWORD The series Advances in the Economic Analysis of Participatory and LaborManaged Firms was launched over 25 years ago by Derek C. Jones and Jan Svejnar. Since then, Advances has been a leading forum for high-quality original theoretical and empirical research in the broad area of participatory and labormanaged organizations. Although general and specialized journals publish work in this field, many do so only occasionally. Advances has been the only annual periodical that presents some of the best papers in the field in a single volume. It is my great pleasure to present Volume 12 of Advances in the Economic Analysis of Participatory and Labor-Managed Firms. Advances has been making frequent use of guest editors. This volume is also ably edited by Jed DeVaro. The selection of Jed as this volume’s guest editor symbolizes the renewed recognition of the importance of theoretical work in the field (Jed is among a few young economists who have been making significant contributions to the field not only empirically but also theoretically). It is my hope that Advances increasingly reflects such renewed interest in theoretical work which will guide empirical studies in more fruitful directions. The scope of Advances will also continue to reflect great changes in the realities of participatory organizations in the last two decades or so. Following the disintegration of the Former Republic of Yugoslavia, the principal systemic example of self-management was replaced with diverse forms of participatory systems. In advanced market economies, many firms have been experimenting with new and innovative work practices aimed at promoting employee participation in decision making in the workplace (sometimes even at the top corporate level) and alternative compensation systems designed to align the interest between labor and management. In addition, a number of significant examples of worker cooperatives have flourished. In transition economies, the collapse of the former USSR triggered widespread experimentation with diverse forms of participation, in particular employee ownership. I hope you will find this volume informative and stimulating and that you will consider contributing to the future volumes of Advances and sharing information about Advances with other interested colleagues.

INTRODUCTION Continuing in the tradition of earlier volumes in the series, the 12th edition of Advances in the Economic Analysis of Participatory and Labor-Managed Firms interprets the themes of the series quite broadly and, consequently, the following pages traverse a highly variegated terrain. I have marked this expansive landscape with four guideposts around which our discussion is organized, namely sections on job design and organizational performance (Part I); compensation, worker attitudes, and productivity (Part II); worker cooperatives and nonprofit organizations (Part III); and free trade and the ecological effects of alternative socio-economic systems (Part IV). The following essays exhibit a diversity of topics, data sources, modes of analysis, geographic contexts, and philosophies. The contributors are similarly diverse, hailing from seven countries, with representation both inside and outside of academia. It is my hope that, in addition to contributing to our knowledge of the broad subject at hand, the articles contained in this volume will inspire productive future work on the important questions addressed herein. The leading article of the volume, and of Part I – which addresses issues of job design and organizational performance – is the jewel by Hideo Owan entitled ‘‘Specialization, multiskilling, and allocation of decision rights.’’ By developing a model that considers the effect of multiskilling on the levels of noncontractible human capital investment, delegation of authority, and unionization, Owan offers another rationale for the multiskilling practices that have been increasingly observed in firms in recent decades. Owan’s key insight is that worker investments in firm-specific human capital become strategic substitutes when their skills overlap each other. Workers compete for bargaining power more intensively when their skills overlap than when they do not. Because of the ‘‘competition effect’’ created by this substitutability, unless specialization offers a substantial technological advantage, then with multiskilling (as opposed to specialization of labor) the following is true: (1) workers’ incentives to invest in firm-specific human capital tend to be stronger; (2) the optimal level of delegation of authority is typically higher; (3) firms’ ex post profits tend to be higher. Firms typically delegate authority to an inefficiently low extent, due to the fear of relinquishing too much bargaining power to workers, but Owan’s analysis shows that multiskilling mitigates this distortion. xiii

INTRODUCTION
Investigating the practice of multiskilling through an empirical rather than a theoretical lens takes us to the second chapter, where Martin Farnham and Emma Hutchinson guide us through an analysis of ‘‘The effect of multiskilling on labor productivity, product quality, and financial performance.’’ Using data from the 2004 British WERS, a nationally representative cross-section of establishments, they measure the effect of multiskilling on establishment-level labor productivity, product quality, and financial performance, finding that accounting for the endogeneity of multiskilling in the empirical models (via bivariate probit analyses) has significant implications for the results. In particular, the estimated (positive) effect of multiskilling on labor productivity disappears after accounting for the endogeneity of multiskilling. Moreover, the estimated effect of multiskilling on product quality goes from zero to positive, and the (positive) effect on financial performance increases significantly in magnitude. The results are important, both because empirical work on the effects of multiskilling on organizational performance is relatively scarce and because such work rarely if ever accounts for endogeneity of multiskilling. The job design discussion then turns from multiskilling to teams, with my work in the third chapter entitled ‘‘Teams, autonomy, and the financial performance of firms: New evidence from panel data.’’ The goal of this chapter is to re-examine, using panel data, the topic I studied five years ago using cross-sectional data, in a paper entitled ‘‘Teams, autonomy, and the financial performance of firms.’’ In the present chapter, I use the 1998–2004 British WERS data to analyze the effect of team production (either autonomous/self-managed or closely managed) on financial performance. The pattern of evidence is consistent with a positive association between team production in an establishment’s largest occupational group and the likelihood of improved financial performance for that establishment. However, the results are mixed concerning whether the positive effects of teams are larger for autonomous teams versus nonautonomous teams. Part II of the volume addresses issues of compensation, worker attitudes, and productivity. A key ingredient in high-involvement and high-performance work systems is premium compensation, which includes generous fringe benefits. A central idea in the economics literature on fringe benefits is the notion of a wage-benefits tradeoff, which is predicted by the theory of compensating differentials. The point is that, in equilibrium, firms and jobs in which relatively generous fringe benefits are paid should be characterized by correspondingly lower wages. From an empirical standpoint, the main challenge to testing for the existence of such substitution is the difficulty of controlling sufficiently for relevant worker, firm, and job characteristics.
Introduction

Even though a number of studies have made impressive attempts to control for such factors comprehensively, an empirical tradeoff between wages and benefits has remained elusive. This naturally leads one to wonder whether there is more to the story than unobserved heterogeneity in workers and employers. Perhaps some other force is contributing to obfuscation of the empirical tradeoff. A natural place to begin looking for such a culprit is by exploring the relevant institutions. Nan Maxwell does just that, in her chapter entitled ‘‘How do rules and costs affect a firm’s setting of benefits? The case of health insurance and workforce skills.’’ Maxwell examines how institutional rules and economies of scale can create incentives for firms to make inframarginal decisions when offering health insurance. Using unique data from the California Health and Employment Survey, she finds results suggesting that failure to control for such inframarginal employer decisions contributes to a failure to empirically identify the wage-insurance tradeoff predicted by ‘‘institution free’’ theory. Among other results, Maxwell documents a 10–13 percentage point increase in the probability of an establishment offering workers health insurance in jobs outside of those in which compensation is being set, if the recruiting difficulty lies in mid- or high-skilled positions. This increase is about twice the size of the increase associated with recruiting difficulty in the position in which compensation is negotiated. One of the lessons from this work, which will hopefully influence the direction of future inquiry on the subject, is that efforts to measure the empirical tradeoff should focus on the employer level rather than the individual worker level. Given the prevalence of powerful institutions in the arena of employer-provided health insurance, it seems almost inevitable that they would heavily influence the wage-benefits tradeoff. More generally, the question of how employers respond to institutional incentives when designing compensation systems is of critical policy importance, particularly given the heated present debate in the United States concerning how health insurance should be provided. Although the workers in Maxwell’s data are nonexecutives, scaling the rungs of the organizational job hierarchy to its peak takes us to the next chapter. There is a large empirical literature on the topic of executive compensation, most of which focuses on Western countries, particularly the United States. Very few studies have addressed compensation in the former Soviet economies and, until the publication of this volume, no work had been done on executive pay practices in Estonia. Jones and Mygind produce the first such work in their chapter entitled ‘‘Majority ownership and chief executive compensation.’’ The authors exploit unique panel data from Estonia to explore the effects of differing types of majority ownership,

INTRODUCTION
including employee ownership, on executive compensation. One of their main results is that an economically significant determinant of executive compensation is ownership, in both state and privatized firms as well as among different types of private firms. A second result is that in firms with majority ownership by employees, compensation is about 15 percent less than in state-owned firms, ceteris paribus. A third result speaks to the oftexplored relationship between firm size and executive compensation. In particular, the authors find much smaller ‘‘firm size elasticities’’ than those estimated in the previous literature based mostly on firms in Western countries. Overall, their results both highlight the varying importance of principal–agent relationships across different types of firms and support a conclusion that privatization has imposed strong discipline on the level of executive compensation. Returning to nonexecutives, the preferences of such workers over various forms of compensation are a central determinant of how employers structure their compensation offerings. An exploration of such worker preferences is undertaken by Fidan Ana Kurtulus, Joseph Blasi, and Douglas Kruse, in their chapter entitled ‘‘Worker attitudes toward different forms of employee ownership and variable pay.’’ The authors use the NBER Shared Capitalism Database, comprised of over 40,000 employee surveys from 14 firms, to investigate worker preferences for employee ownership, profit sharing, and variable pay using detailed survey questions pertaining to those forms of compensation. Of primary interest is how preferences for those various types of output-contingent pay vary with worker risk aversion, residual control, and perceptions of co-workers and management. The main results of the paper reveal that, on average, workers prefer to have at least part of their compensation be performance-related, with stronger preferences for output-contingent pay among workers who have lower levels of risk aversion, greater control over the work process, and greater trust of co-workers and management. The Kurtulus–Blasi–Kruse chapter focuses on worker preferences which, as noted, are a key determinant of various forms of output-based pay. In addition to considering the determinants of output-based pay, an important area of research in the empirical incentives literature concerns the consequences of such output-based pay, and in particular the consequences for performance. That topic is addressed in the context of the Italian economy in the chapter by Mirella Damiani and Andrea Ricci entitled ‘‘Performancerelated pay, unions and productivity in Italy: Evidence from quantile regressions.’’ The authors explore the relationship between performancerelated pay and productivity using a nationally representative sample of manufacturing and service companies. In the first of two steps, the authors

estimate a classical production function using longitudinal data on the balance sheet variables of firms during 2002–2005. In the second step, they regress the distribution of the firm-specific fixed effects on indicators for performance-related pay and unions and on year-2005 controls. The main result is that adoption of performance-related pay is positively associated with productivity throughout the whole distribution and that the presence of unions is positively associated with firms’ unobserved productivity across all quantiles, being significantly higher for those firms at the highest quantile of the productivity distribution. Part III of the volume addresses worker cooperatives and nonprofit organizations.In her chapter entitled, ‘‘Profit reinvestment in Italian worker cooperatives as a contribution to a common good: an empirical analysis on workers’ perception and motivation,’’ Cecilia Navarra applies tools from the collective action literature to explain the high propensity of Italian worker cooperatives to reinvest profits into asset locks, i.e. common funds that are nondivisible and nonappropriable by individual members, neither when they retire nor at the end of the cooperative’s life. Funds contributed to asset locks cannot be distributed to members and must be used only for the firm’s overall purposes. Navarra characterizes asset locks as a common pool resource, creating a collective action problem that may appear in two forms: free-riding in effort provision and an inter-temporal incentive problem whereby current generations have an incentive to underinvest in the common pool resource given that they will not reap the future dividends from those investments. Navarra asks what individual characteristics (i.e. collective or groupbased motivation, and attitudes toward time preference) facilitate a cooperative willingness to reinvest profits in the firm. To shed light on this, she uses a survey of a sample of workers in cooperatives affiliated with the Legadelle Cooperative e Mutue of the province of Ravenna, Italy, to illuminate the attitudes of workers towards asset locks. She finds some evidence suggesting a higher degree of loyalty to firms that amass a greater share of profits into asset locks. However, she cannot determine whether this arises because of repeated interactions or because of the employment insurance provided by the cooperative. Workers identified as having a positive attitude toward asset locks exhibit a preference for the relational aspects of the job and for ‘‘on-the-job’’ consumption. Members who participate in the decision on profit allocation are found to be more willing to reinvest profit into asset locks. A striking result is that employees are, on average, more likely to favour asset locks than are worker-members, which Navarra explains by noting that only members participate in profit sharing.

INTRODUCTION
In his essay at the end of this volume, Jaroslav Vanek cites as an illustrative example the well-known Mondragon cooperatives of Spain. These coops are the focus of a case study on training, recruitment, and retention, conducted by Imanol Basterretxea and Eneka Albizu in their chapter entitled ‘‘Does training policy help to attract, retain, and develop valuable human resources? Analysis from the Mondragon case.’’ The authors aim to investigate the extent to which a training policy developed through corporate training centers is recognized by HR managers as a source of competitive advantage for attracting, developing, and retaining valuable employees. Their descriptive analysis is based on the case of the Spanish Mondragon cooperative group and, in particular, a survey of HR managers from 66 cooperatives in the group. The main result of the descriptive analysis is that, in the eyes of HR managers, Mondragon’s training policy is perceived to be a useful tool for attracting, developing, and retaining valuable human resources. The results also suggest that the aforementioned advantages of training policies are more modest than has been recognized in the literature on Mondragon. Focusing on the perceptions of HR managers is potentially important, to the extent that such managers influence policy regarding the recruitment, screening, and training of new workers, as well as strategies to retain new hires that reveal themselves to be of high value. It can be helpful, if we want to understand how various practices affect organizational performance, to learn the perspectives of those who administer and in some cases propose and design these practices. Data arising from survey questions of the type analyzed here potentially suffer from a variety of biases and this, along with the fact that the tabulations the authors report are basic and unconditional, should be kept in mind when interpreting the results. Among other concerns, one might worry that a manager’s perception of the success of a program is likely colored by the fact that the program was adopted in the first place. It can be expected that HR managers may think more positively about programs that have been purposefully adopted, perhaps with their input. Concerns also arise about how managers interpret various questions, and about the scarcity of quantifiable effects (e.g., we might learn that HR managers believe that training improves retention, but of ultimate interest is the magnitude by which a given expenditure on training improves retention). Another concern is the survey’s undue focus on benefits and not on costs. So we might learn that HR managers believe that ‘‘Offering more continuous training than competitors helps us to retain valuable staff,’’ but doubling everyone’s compensation would accomplish the same thing, and in the absence of further information, there is really no reason to

prefer one of these HR practices over the other. These data issues notwithstanding, the chapter offers food for thought and should encourage further exploration of the topic in future work. Bouncing from the Mondragon cooperatives of Spain down to the southern hemisphere takes us to the next chapter. A growing literature studies differences between for-profit firms and nonprofit organizations. Less attention has been devoted to comparing different types of nonprofits or other nontraditional firms, and that is the goal of Juan Jose Barrios and Mieke Meurs in their chapter entitled ‘‘Governance and behavior in nonprofits: Analysis of Uruguayan health care organizations.’’ The authors use a unique data set to examine differences across three types of Uruguayan nonprofit health care organizations. Their main result is that the structure of stakeholding and governance significantly affects behavior even where many behaviors are highly regulated, and their findings highlight the importance of carefully specifying stakeholder and governance structure when predicting the behavior of nonprofits. Part IV concludes the volume with a debate on the subject of comparative economic systems and the implications for the environment. In a provocative essay entitled ‘‘Capitalism, economic democracy, and ecological destruction of our planet’’ the venerable Jaroslav Vanek takes the stage to ignite a lively debate on the virtues and vices of capitalist economic systems versus fully democratic systems from the standpoint of the ecological wellbeing of the planet. Vanek argues that fully democratic systems of economic organization, which rely on democratic decisions based on personal rights in areas such as enterprise management and organization, are in many cases particularly well suited for protecting the natural environment. The logic is that the decision makers in such democratic systems live in and are permanently exposed to the environment, creating natural incentives to protect it. In contrast, in capitalist economic systems, firms are interested solely in maximizing profits, focusing on their private costs of production as opposed to social costs and ignoring the negative environmental production externalities associated with their activities. Consequently, Vanek concludes that public regulation is of greater necessity for capitalist firms than for firms in fully democratic economic systems. In counterpoint to these arguments, I join Adrian Stoian in presenting a case for the capitalist system. In a brief rejoinder following our comment, Vanek closes the debate and also this volume with some views on the destructive potential of free trade. Jed DeVaro Guest Editor
PART I JOB DESIGN AND ORGANIZATIONAL PERFORMANCE
SPECIALIZATION, MULTISKILLING, AND ALLOCATION OF DECISION RIGHTS Hideo Owan ABSTRACT The purpose of this chapter is to offer new justification for multiskilling practices such as job rotation and extensive training for broad skills and explain why there appear to exist complementarity between multiskilling and the delegation of decision authority to workers. By developing a new model of incomplete contracting where workers make noncontractable investments in multiple skills, we obtain the key insight that worker investments in firm-specific human capital become strategic substitutes when their skills overlap each other. The ‘‘skill substitution effect’’ analyzed in this chapter induces the following three major results, unless specialization offers a substantial technological advantage: (1) workers’ incentives to invest in firm-specific human capital tend to be stronger; (2) the optimal level of delegation is typically higher; and (3) firms’ ex post profits tend to be higher with multiskilling than with specialization.

The novel implication of the chapter is that multiskilling may be desirable from a firm’s viewpoint even if there are no technological or informational task complementarities among the combined skills, which have been believed to be primary reasons for multiskilling in prior works.

INTRODUCTION One of the most drastic changes in economists’ views on job design in the past few decades is their recognition of the gains from multiskilling vis-a-vis specialization.1 The idea that specialization and division of labor allow more output from a given set of inputs has been embraced by economists because numerous anecdotes (including Adam Smith’s famous description of a pin factory) and historical productivity data supported the proposition. Obviously, a number of economists, including Adam Smith, have discussed the factors that ultimately limit specialization (e.g., size of markets and complementarity among tasks).2 However, scrutinizing trade-offs affecting the optimal division of labor have become more important recently due to a current trend toward job enlargement. A number of authors have attempted to explain basic trade-offs determining job design. Becker and Murphy (1992) assert that the degree of specialization is constrained by various costs of coordinating specialized workers who perform complementary tasks and the amount of general knowledge available for each task. A similar view is presented by Bolton and Dewatripont (1994), who argue that the benefits of greater specialization in information processing by having more agents team up within the same organizations are partly (and sometimes entirely) offset by the increased costs of communication within the enlarged group of agents. These theories, however, cannot explain why we are observing more workplaces adopting multiskilling practices recently. For example, they imply that falling costs of coordination and communication due to advancement in information technology should encourage specialization, not multiskilling. Koike (1977, 1988) is perhaps the first author to emphasize the improvement of problem-solving skills as the most important benefit of
Specialization, Multiskilling, and Allocation of Decision Rights

multiskilling. According to his extensive research of Japanese automobile plants, job rotation and other multiskilling practices prevalent in those plants help workers to understand the whole process and acquire capabilities to respond to productivity and quality issues as they arise in the workplace.3 Lindbeck and Snower (2000) also focus on a difference in learning patterns between ‘‘tayloristic’’ (characterized by specialization) and ‘‘holistic’’ (characterized by multiskilling practices) work organizations. They distinguish two types of learning, ‘‘intratask’’ and ‘‘intertask’’ learning, where the former is traditional learning-by-doing best attained by performing a narrow task, and the latter arises when a worker can use the information and skills acquired at one task to improve his performance at other tasks. Employers then face a trade-off between returns to specialization, which enhances intratask learning, and returns from task complementarities, which accumulate through intertask learning. They argue that a shift toward holistic organizations has been driven by four forces, including advances in production technologies promoting technological task complementarities, advances in information technologies promoting informational task complementarities, changes in worker preferences in favor of versatile work, and advances in human capital that make workers more versatile. Some benefits of multitasking are also mentioned as part of the discussions on complementarities supporting team-based high-performance work systems. Firms adopting a certain bundle of human resource and work practices typically including autonomous teams, contingent compensation, job rotation, extensive training, and worker involvement for quality improvement are found to have experienced substantial improvement in productivity as well as product and service quality.4 Common features seen in these workplaces are an emphasis on the development of multiskilled workers, the sharing of information, and the delegation of responsibilities to teams. Milgrom and Roberts (1990, 1995) offer a coherent theory of complementarities among the firm’s choices of technologies and practices, using the framework of monotone comparative statics. They show that a fall in the costs of flexible manufacturing equipment or of computer-aided design equipment lead to systematic responses including more frequent product redesigns and improvements, speedier delivery, more efforts to reduce setup and changeover costs, and so on. These changes in the firm’s incentives are expected to encourage investment in process innovations and to increase the returns to cross-training and greater autonomy for workers because the latter two practices are assumed to lower the cost of process innovations. The relative optimality of teamwork or tasksharing has also been extensively analyzed by Holmstrom and Milgrom (1991) and Itoh (1991, 1992, 1994).

HIDEO OWAN
In this chapter, we offer another justification for multiskilling practices, which is distinct from the existing literature in two aspects. First, according to our theory, skill complementarities are not necessary for multiskilling to arise as the optimal practice for firms. In other words, multiskilling may be desirable from a firm’s viewpoint even if there are no technological or informational task complementarities among the combined skills. Second, our framework can explain why there appear to exist complementarity between multiskilling and the delegation of decision authority to workers, two essential elements in the high-performance work systems as discussed earlier. We use the Grossman–Hart–Moore framework of incomplete contracting where neither job design consisting of tasks, decision authority, and skill sets nor human capital investment are contractible and wages are determined by ex post bargaining. The solution concept we use is the Shapley value. Unlike Grossman and Hart (1986) and Hart and Moore (1990), the ownership structure is not our concern here. We show that an organization with a job design that relies on multiskilled workers (henceforth, an M-organization) significantly weakens workers’ bargaining power but somewhat paradoxically raises their incentive to acquire firm-specific skills. The key insight provided by the model is that worker investments in firm-specific human capital become strategic substitutes when their skills overlap each other as a result of multiskilling. With this substitutability, it is intuitive that workers’ bargaining power relative to the owner-manager is weaker in the M-organization than in one with a specialized work force (henceforth, an S-organization), other things being equal. Less intuitive is that workers are more motivated to invest in firm-specific skills in the M-organization. This incentive comes from the fact that a worker’s broad skills in the M-organization become more valuable when other workers whose skills overlap with the first one are absent. Note that the Shapley value of worker i, our solution concept of bargaining outcome, can be expressed as the weighted average of marginal contribution of worker i in all possible subgroups. With skill substitutability, a worker’s broad skills in the M-organization tend to be more valuable in small subgroups containing the owner of the firm than in the S-organization. As a result, a worker’s wage expressed as the Shapley value tend to be more sensitive to the accumulation of firm-specific human capital in the M-organization than in the S-organization. To sum up this argument, human capital substitutability in the M-organization lowers the return to bargaining, but raises the elasticity of bargaining returns with respect to human capital investment. Intuitively, workers compete for bargaining power more intensely when their skills overlap than when they do not.5,6

One question that needs to be addressed concerning the setup of our theory is whether skill overlapping is in fact what we observe in those organizations that have adopted multiskilling practices. Given the fixed numbers of workers and skills needed, multiskilling seems to require a greater degree of overlapping. One notable example that demonstrates the prevalence of increasingly overlapping skills is autonomous work teams that are perceived as an essential element of the flexible work systems discussed earlier. In a typical autonomous work team, workers make decisions together and coordinate activities, and to facilitate such a high level of coordination, team members need to know one another’s job very well and share information. Job rotation is used to make members learn one another’s job. Here, overlapping skills are not just a consequence of multiskilling. Quite the contrary, the latter is introduced to achieve the former. In our theory, whether overlapping skills enhance productivity or not does not matter, but they do generate a ‘‘skill substitution effect,’’ which drives all of our results. We believe that many accounts of flexible work systems (see note 4 for references) suffice as evidence of a prevailing tendency toward skill overlapping. Although the mechanism we find is innovative as an explanation for the rationale for multiskilling practices, a similar mechanism has been identified in other contexts. For example, Edlin and Hermalin (2000) analyze the situation where both the principal and the agent invest in an asset that has greater value if owned by the principal than by the agent. They show that when the principal and agent’s efforts are substitutes, the possibility of renegotiation encourages the agent to overinvest to strengthen his bargaining position. This research is also closely related to that of Stole and Zwiebel (1996b), which studied how organizational design and technology choice by a firm with no binding employment contracts differ from those of a neoclassical firm with no ex post wage bargaining. Our work enriches their model by endogenizing investment in firm-specific human capital and examines how organizational design affects the workers’ skill formation in a firm with no binding employment contracts. We further extend our framework to analyze managers’ decisions on how much authority they should delegate to the workers. Aghion and Tirole (1997) have developed a theory of the allocation of decision rights (formal authority) in situations where the decision-maker, if uninformed, can communicate with the informed party, who in such a case has effective control over decisions (real authority). In their model, the principal can provide more incentives to the agent by delegating formal authority to him (at the cost of losing control) because it raises the agent’s chance of gaining

effective real control and thus more private benefit. Similarly, in our model, the delegation of more decision authority motivates workers to invest more because capabilities to make good decisions become more valuable if the workers have more decision rights. Our ‘‘incomplete contract’’ assumption induces our key insight that the owner-manager typically delegates a less than optimal amount of responsibilities to the workers. Results similar to this have been obtained by Freeman and Lazear (1995) and Prendergast (1995). Our novel finding is that the substitutability of worker skills in the M-organization encourages the manager to delegate more decision rights because the marginal wage increase due to delegation is smaller but an increase in the workers’ incentives to acquire skills is greater in the M-organization. For a large set of production technology, the optimal level of delegation is typically higher in the M-organization. As our basic model assumes individual bargaining and individual decision-making on skill investment, it is natural to ask how collective bargaining and jointly choosing skill investment might affect our results. As Horn and Wolinsky (1988) and Stole and Zwiebel (1996b) have already proved, workers gain by forming a union and engaging in collective bargaining when their human capital stocks are substitutable. Therefore, the workers in the M-organization can expropriate more surplus by unionizing ex post. However, unionization harms the workers’ incentive to acquire skills because union wage as defined as an outcome of collective bargaining is less sensitive to individual human capital investment. Worker cooperation in choosing skill investment should be encouraged in a unionized firm because it mitigates free-riding, while it should be discouraged in a nonunionized firm because cooperation eliminates the ‘‘competition’’ for bargaining power in the skill investment stage discussed earlier. This implies that workers should not be involved in planning training and should be rotated between teams to discourage cooperation in skill investment in a nonunionized setting, but the converse is true in a unionized firm. We begin the second section by introducing the simple model in which two workers solve two different decision problems that require distinct skill sets. Workers make noncontractable efforts to acquire skill sets that enhance the probability of finding the best solutions for respective decision problems. We show that both specialization and multiskilling could appear in the equilibrium. In the third section, we provide the basic findings of examining the effect of multiskilling on workers’ wages and the levels of their skill investment. In the fourth section, we extend the model so that the ownermanager of the firm allocates the set of decision rights between herself and the

workers to see the effect of multiskilling on the optimal allocation of decision authorities. In the fifth section, we consider the effect of collective bargaining and worker cooperation in choosing skill investment on the equilibrium level of human capital, which offer a number of implications about unionization, worker training, and job rotation. The sixth section provides a general discussion of what factors affect the firm’s choice of organizational form and the seventh section offers concluding remarks.
BASIC MODEL This study deals with two distinct policies of job design: one under which workers are specialized in one task and encouraged to acquire deep, narrow skills; and one under which workers are multitasking and motivated to learn broad skills that overlap with others. We call the former organization the Sorganization and the latter the M-organization. Unlike Grossman and Hart (1986) and Hart and Moore (1990), ownership structure is not our concern. Hence, we simply assume that an owner-manager owns assets for production and hires two homogeneous workers in the market.7 The ownermanager and the workers are denoted by M, and i (i ¼ 1,2), respectively. Both the manager and the workers are risk-neutral.
Technology Suppose the firm needs to solve two decision problems denoted by k where k ¼ 1,2. The outcome of each decision is either success or failure and the firm’s output from a successful decision is m while a wrong decision generates no output. Each decision problem k requires a different firmspecific and problem-specific skill set Ak. A worker who invested in Ak can solve problem k better. Let xi,k denote worker i’s investment in skill set Ak, and let xi ¼ (xi,1, xi,2) and X ¼ (x1, x2). The personal cost of investment is c(xi). Worker i with investment xi,k can find a right solution for problem k with probability P(xi,k). P is concave and twice continuously differentiable, and P(0) ¼ 0. We assume that the discovery of a solution is stochastically independent across workers. In other words, workers obtain solutions based on their idiosyncratic private information observed in the workplace. Let v denote the value the owner-manager can create using her assets and workers with no skills (i.e., xi,k ¼ 0 for all i and k.). We can set v ¼ 0 for the moment but later assume that v depends on the allocation of decision rights.

The probability that either worker finds a right solution for problem k is 1(1P(x1,k))(1P(x2,k)). Then, the expected joint output is as follows: YðXÞ ¼ v þ m

The manager owns the firm in the sense of Hart and Moore (1990), and thus, the workers cannot produce anything without management. A worker with no firm-specific human capital produces nothing (i.e., P(0) ¼ 0), and the worker’s outside option value is assumed to be zero. When a worker leaves the firm after investment in firm-specific skills, he will be replaced by a new hire who has no firm-specific skills. The expected output when one or two workers leave can be easy derived. With only worker i remaining, the output is v þ m(P(xi,1) þ P(xi,2)) (i.e., xiu ¼ (0, 0) for iu 6¼ i). With both workers replaced, the surplus is v. To rule out asymmetric Nash equilibria, we impose the following assumptions: Assumption 1:
P0 ðxÞ is decreasing in x 3 2PðxÞ
Assumption 2:
cðxi;1 ; xi;2 Þ ¼ cðxi;1 þ xi;2 Þ
Assumption 1 requires that P(x) does not converge to 1 too quickly as x increases. In other words, it ensures that increased investment by one worker does not make the returns to the other’s investment fall too quickly. When Assumption 1 is violated, it could be efficient to assign both decision problems to one worker and let him alone invest substantially in skills. But this case is not of much interest in light of our motivation because in such asymmetric equilibrium, there is no trade-off in specialization and multiskilling. It should also be noted that Assumption 1 is sufficient to rule out any equilibria other than S-organization and M-organization as Proposition 1 notes.8 Assumption 2 assumes perfect cost substitution. By imposing Assumption 2, we can simplify our comparison of specialization and multiskilling in determining bargaining power and human capital investment. Another possibility is the cost function with skill complementarity under which acquiring one skill set helps workers to learn another skill set. Skill complementarity, however, substantially favors multiskilling, obscuring the role of human capital substitutability in multiskilling organizations. Additionally, we assume that c is convex and twice continuously differentiable and that cv(x)/cu(x) is nonincreasing with c(0) ¼ 0 and

limx-Nc(x) ¼ þN. To ensure the equilibrium with positive investment, we assume the following: Assumption 3:
m 0 P ð0Þ4c0 ð0Þ 2
One example of P satisfying Assumption 3 is P(x) ¼ 1 ex, which will be frequently used throughout the chapter.
Wage Bargaining We assume that X is observable, but that neither X nor the actual outputs are verifiable. Hence, the manager cannot offer a contract contingent on any of these variables including the ‘‘sell the job’’ contract under which the workers pay a fixed amount to the owner-manager in exchange for the income stream from their decisions. The timing of decision-making is as follows. The workers choose the level of investment x1 and x2. After the profile of investment X is observed by all, the owner-manager and the workers negotiate wages. Finally, after wages are determined, the owner-manager and the workers make decisions and generate surplus. We assume that the wages are determined by the Shapley value. The Shapley value for worker i is the weighted average of his marginal contribution in all possible subgroups. The weights are calculated based on the number of all possible sequence combinations that form the subgroup.9 A non-cooperative game theoretical justification of the Shapley value is provided by Stole and Zwiebel (1996a). In their model, the manager and the workers bargain pairwise sequentially and, in each session, play the alternating-offer bargaining game of Binmore, Rubinstein, and Wolinsky (1986), in which there is an exogenous probability of breakdown. The solution for this game is the Shapley value for the corresponding cooperative game in the limit. Later, we will also consider collective bargaining in which the union bargains with the owner-manager over the total wage. Under the bargaining structure explained above, worker i’s wage is determined by the following: m m m wi ðXÞ ¼ Pðxi;1 Þð1 Pðxj;1 ÞÞ þ Pðxi;2 Þð1 Pðxj;2 ÞÞ þ ðPðxi;1 Þ þ Pðxi;2 ÞÞ 3 3 6 (2)

Note that because the workers’ human capital investment is firm-specific, the subgroup without the owner (i.e., workers who leave the firm and form a new group) cannot produce any outputs. As a result, the bargaining return to his investment is less than the total return to the investment. This is the famous holdup problem. The profit the owner-manager earns is as follows: pðXÞ ¼ YðXÞ w1 ðXÞ w2 ðXÞ m ¼ v þ ðPðx1;1 Þ þ Pðx1;2 Þ þ Pðx2;1 Þ þ Pðx2;2 ÞÞ 2 m ðPðx1;1 ÞPðx2;1 Þ þ Pðx1;2 ÞPðx2;2 ÞÞ 3

Nash Equilibrium in the Investment Game First, we show that both specialization and multiskilling could arise endogenously when workers optimally choose investment in skill sets. In the equilibrium, the following first-order conditions have to be satisfied: @wi m m ¼ P0 ðxi;1 Þð1 Pðxj;1 ÞÞ þ P0 ðxi;1 Þ c0 ðxi;1 þ xi;2 Þ @xi;1 3 6 @wi m m ¼ P0 ðxi;2 Þð1 Pðxj;2 ÞÞ þ P0 ðxi;2 Þ c0 ðxi;1 þ xi;2 Þ @xi;2 3 6

where i ¼ 1, 2. The following proposition proves that there could appear only two different Nash equilibria under Assumption 1: symmetric specialization and symmetric multiskilling. Proposition 1. There could be at most two Nash equilibria in the stage game where two workers choose their investment profiles. In one equilibrium x11 ¼ x12 ¼ x21 ¼ x22 . When m6 P0 ð0Þð3 2Pðx ÞÞ c0 ðx Þ for the solution x to the equation m6 P0 ðx Þð3 2Pð0ÞÞ ¼ c0 ðx Þ, there is another equilibrium, in which xi1 ¼ xj2 ¼ x and xi2 ¼ xj1 ¼ 0. Proof. See the appendix. Proposition 1 ensures that workers choose the same investment level and invest either uniformly between the skill sets or specialize in one skill set. There is no asymmetric equilibrium where workers choose different

13
investment levels or invest in both skill sets but do so asymmetrically. Although ‘‘multiskilling’’ equilibrium always exists, ‘‘specialization’’ equilibrium may not exist unless there is some gain from specialization. k To make this point clear, consider PðxÞ ¼ 1 ex where k is a parameter of gains from specialization and kW0. The higher the value of k, the more likely is specialization to be efficient. We can easily show that ‘‘specialization’’ equilibrium exists if kW1 but does not if kr1. Firm’s Choice of Job Design Proposition 1 allows us to focus on the two types of job design: specialization and multiskilling. In the rest of our analyses, we assume that the owner-manager can first choose either type of job design. Such assumption is reasonable for two reasons. First, when both equilibria in Proposition 1 exist (i.e., there are some gains from specialization), the owner-manager should be able to induce the equilibrium with more profitable outcome to realize by guiding workers’ beliefs. For example, management can express its expectation and offer training opportunities to encourage a certain learning behavior. Second, the owner-manager can directly control the skill sets that workers acquire by offering specific training programs or complementary practices (e.g., team activities, job rotation, and evaluation) designed for either specialization or multiskilling. We call organizations with specialized skill investment S-organization and those with multiskilling practices M-organization. Let xi be the total investment made by worker i. Namely, xii ¼ xi in the S-organization and xi1 ¼ xi2 ¼ x2i in the M-organization. Then, by substituting these investment choices into Eq. (1), the expected outputs in the S-organization and M-organization, YS and YM respectively, are expressed as follows: Y S ðx1 ; x2 Þ ¼ v þ mðPðx1 Þ þ Pðx2 ÞÞ

h x x i 1 2 Y M ðx1 ; x2 Þ ¼ v þ 2m 1 1 P 1P 2 2
(6)
Likewise, we can compare the wage functions in S-organizations and M-organizations. Let wSi ðx1 ; x2 Þ and wM i ðx1 ; x2 Þ be the worker i’s wage in the S- and M-organizations, respectively. Then, from Eq. (2), we get 1 wSi ðx1 ; x2 Þ ¼ mPðxi Þ 2

wM i ðx1 ; x2 Þ

(7)
The key difference between these two wage functions is that there is no interaction between x1 and x2 in wSi , whereas x1 and x2 are Edgeworth 10 2 S M M This feature drives most of substitutes in wM i (i.e., @ wi =ð@x1 @x2 Þo0). our results that follow.
BASIC RESULTS As a first step to see what factors affect the relative efficiency of the Sorganization and the M-organization, we compare the production frontiers of the two organizations. By substituting x1 ¼ x2 ¼ x into Eqs. 5 and 6, we obtain the following: x2 41 PðxÞ (8) Y S 4Y M if 1 P 2 The condition requires that the marginal increase of P does not decrease too quickly. When it is satisfied, there are gains from specialization. Again, k let us assume PðxÞ ¼ 1 ex . Then, inequality (Eq. (8)) holds if and only if M S k W1 and Y ¼ Y for all x when k ¼ 1. In many results in the chapter, we k assume this specific function of PðxÞ ¼ 1 ex , with which an increase in k raises the relative efficiency of the S-organization. The next proposition investigates how an organizational difference affects the workers’ bargaining power. Proposition 2. 1 wSi ðx; xÞ ¼ ðY S ðx; xÞ Y S ð0; 0ÞÞ 4 1 M m x 2 M wi ðx; xÞ ¼ ðY ðx; xÞ Y M ð0; 0ÞÞ P 4 6 2 The proof is omitted because it is straightforward from Eqs. (4)–(7). In the S-organization, the owner-manager and the workers split the quasirent by half and each worker receives one quarter. Hence, the wage in the S-organization is the same as the union wage if collective bargaining leads to a Nash bargaining solution. In the M-organization, a worker receives less than one quarter of the quasi-rent because of his weaker bargaining power. Namely, in the M-organization, when one worker quits, the output does not

drop as sharply as in the S-organization because of the overlapping investment in the same skill set made by the other worker. Put differently, the loss of human capital caused by the separation is partly offset by the more efficient use of the other worker’s broad skills. Because worker turnover is less costly for the firm as a result, the M-organization should give its workers lower wages, given the same amount of investment. The difference 2 in the bargaining power is captured by the last term m=6 P x=2 . Propositions similar to this have been proven by Horn and Wolinsky (1988) and Stole and Zwiebel (1996b). They find that workers bargaining with the employer gain by forming a union when they are substitutable to one another and lose when they are complementary. In our model, workers in the M-organization is introduced, will receive 14 ðY M ðx; xÞ Y M ð0; 0ÞÞ when collective bargaining 2 and therefore, the union wage is higher by m=6P x=2 in the M-organization. Let x~ S and x~ M be the efficient total investment in the S- and Morganizations, respectively.11 Also, denote the equilibrium investment for the S and M-organizations by xS and xM , respectively. As the owner-manager can capture a share of the surplus created by the workers’ investment (i.e., the holdup problem), the workers underinvest in skills in the S-organization. Namely x~ S 4xS . In the M-organization, however, the investments are substitutes and thus subject to a countervailing effect: a worker’s investment increases his marginal contribution to a subgroup containing only him and the owner more than his marginal contribution to the total output because his broad skills are more valuable without a coworker whose skills overlap with his. A mechanism working behind the Shapley value formula is that a worker’s human capital investment weakens the other worker’s bargaining position, which in turn generates additional negotiation surplus for the former. More intuitively, an increase in one worker’s investment makes it more likely that the other’s discovery of the solution is redundant, reducing the value of the other’s skills. I will call this the ‘‘skill substitution effect.’’ In an extreme case, the workers could overinvest in skills in the M-organization. To see this point, compare the first-order conditions for x~ M and xM . The efficient investment x~ M is obtained by solving the following: x x @Y M 1P c0 ðxÞ ¼ 0 ðx; xÞ c0 ðxÞ ¼ mP0 (9) 2 2 @xi xM solves x m x @wM m x i ðx; xÞ c0 ðxÞ ¼ P0 1P þ P0 c0 ðxÞ ¼ 0 3 2 2 6 2 @xi

(11)
Skill substitution effect
¼0 In the M-organization, when the skill substitution effect is greater than the holdup effect, the workers overinvest in skills.12 As we discussed in the section on Introduction, Edlin and Hermalin (2000) find a similar effect that offsets the holdup effect in a model with substitutable investments made by the buyer and the seller of an asset. Because of the skill substitution effect discussed earlier, the M-organization tends to give the workers stronger incentives to acquire skills if the individual bargaining procedure is adopted. This comparison is more clearly stated when we assume P(x) ¼ 1ex. With this production technology, YS ¼ YM for any symmetric investment x1 ¼ x2 ¼ x. Therefore, x~ S ¼ x~ M . Despite the fact that the wage is lower in the M-organization than in the S-organization, the former outperforms the latter in terms of productivity as shown in the next proposition. Proposition 3. When P(x) ¼ 1ex, xM 4xS . Proof. Suppose x1 ¼ x2 ¼ x. Then, @wM @wS m x x i ðx; xÞ i ðx; xÞ ¼ e2 ð1 e2 Þ40 @xi @xi 6 for all xW0. Hence, xM 4xS . Propositions 2–3 imply that when the two organizational forms have the same production frontier, firms should choose an M-organization because it induces higher investment and gives the owner-manager a larger share of the economic rent earned.
ALLOCATION OF DECISION RIGHTS In the previous sections, the manager has played only a limited role in determining the firm’s output because v is constant. In this section, we
Specialization, Multiskilling, and Allocation of Decision Rights
17
assume that the owner-manager allocates decision problems to the workers. In so doing, a manager has to decide how many decision rights she should delegate or, in other words, how much the workers should be ‘‘empowered.’’ Let S be the set of all decision problems. There exists a partition S ¼ S1 , S2 where skill set Ak is necessary to solve problems in Sk. Decision problems in S are ordered according to the relative advantage of the manager to the workers in making right decisions. The decision problems that are high in this ordering are more strategic decisions, and the manager’s ability to coordinate decisions between S1 and S2 gives her relatively high productivity. The decision problems that are low in this ordering are more operational decisions, and the workers’ engagement in the production process enables them to create relatively high value on these lower-order problems. The manager’s problem is simply to choose the set of decision rights she will delegate to the workers. This set is Sr ¼ S1,r , S2,r where r A [0, 1] is the delegation parameter that represents how much the workers are empowered and Sk,r C Sk. We assume that there is a continuum of decision problems and r is continuous. r ¼ 0 indicates that no decision rights are delegated to the workers, and r ¼ 1 means all decision problems are assigned to the workers. Sr is nondecreasing in r in the set order. Let z(r) denote the average incremental value created by a worker from a successful decision on s A Sr and Z(r) denote the average incremental value created by the manager for s A S\Sr. The size of the allocated responsibility affects the quality of implementation and thus the value created by successful decisions: z(r) is decreasing in r, and Z(r) is increasing in r. As before, P(xi,k) is the probability that worker i with investment (xi,1, xi,2) will find a right solution for s A Sk,r, and we assume the same properties for P as in the previous sections. The firm’s expected joint output is as follows: 2 X #ðS k;r Þ½1 ð1 Pðx1;k ÞÞð1 Pðx2;k ÞÞzðrÞ YðX; rÞ ¼ #ðS\Sr ÞZðrÞ þ k¼1
where #(Z) denotes the number of decision problems in Z. Assume #(S1,r) ¼ #(S2,r) and redefine v(r) ¼ #(S\Sr)Z(r) and m(r) ¼ #(Sk,r)z(r). Then, the output function looks similar to Eq. (1) except that the productivity coefficients are parameterized by r as follows: 2 X ½1 ð1 Pðx1;k ÞÞð1 Pðx2;k ÞÞ (12) YðX; rÞ ¼ vðrÞ þ mðrÞ k¼1

We assume that r is not contractible. Otherwise, ex ante transfers can be made contingent on the decision rights delegated to the workers and the firm can achieve the efficient delegation by simply ‘‘selling’’ decision rights to the workers. Here, the owner-manager is expected to choose r so as to maximize her ex post bargaining surplus. We also assume that once the ownermanager delegates the set of decision rights Sr to the workers, she is unable to solve any problems in S\Sr after the skill investment is made.13 The interpretation is that the owner-manager loses access to the opportunities to learn problem-specific knowledge and information that the workers acquire after delegation. As the owner-manager cannot take over any subset of delegated decision rights ex post when one or two workers leave the firm, the profit function is identical to Eq. (3) except for the parameterized coefficients v(r) and m(r). To facilitate mathematical derivation, let v and m be twice continuously differentiable. To ensure unique interior solution, we assume vv r 0, vu(0)W0, vu(1)o0, mv r 0, mu(0)W0, and mu(1)o0. The concavity of v and m also makes it suboptimal for the owner-manager and the workers to share authority and exchange information. Now we ask how increased allocation of decision authority affects the workers’ incentives to acquire skills. Consider the S-organization as before. The workers solve 1 max wSi ðr; x1 ; x2 Þ cðxi Þ ¼ mðrÞPðxi Þ cðxi Þ x 2 From the first-order condition 1 mðrÞP0 ðxi Þ ¼ c0 ðxi Þ 2

The owner-manager will optimize with respect to r, assuming that workers will choose investment optimally. Let pS ðr; xS Þ and let pM ðr; xM Þ denote the profit functions for the owner-manager in the S- and M-organizations, respectively. Then, pS ðr; xS Þ ¼ vðrÞ þ mðrÞPðxS Þ

vuW0 implies that the owner-manager’s productivity increases as his responsibilities decrease. This means that the owner-manager is overloaded in the range where vuW0. Similarly, the workers are overloaded when mu(r)o0. In Assumption 4, we assume that the owner-manager and the workers cannot be overloaded at the same time. In order words, the set of decision rights S should not be too large for three people to handle. Assumption 4:

There are two channels through which an increase in r affects the ownermanager’s profit: (1) through a direct impact on productivity and bargaining power and (2) through an indirect impact via a change in worker incentives. Let rl be the optimal degree of delegation for the l-organization. The next lemma is used in the following results. Lemma 1. m0 ðrl Þ40 for l ¼ S,M. Proof. We prove only for the S-organization.

Suppose m0 ðrS Þ 0. The term in the last brackets is positive. Then, Assumption 4 implies that dpS =drðrM Þo0, leading to contradiction. This concludes the proof. Now we compare the owner-manager’s optimal choice with the efficient allocation r~l that maximizes the total surplus created in the firm, Y l ðr; xl ðrÞÞ 2cðxl ðrÞÞ. Note that the efficient allocation discussed here does not assume efficient investment in skills. Thus, its efficiency is constrained by the workers’ self-interested choice of skill investment. Proposition 4. The owner-manager always underdelegates decision rights to the workers in the S-organization. Underdelegation also appears in the M-organization if the cost function is well-behaved. r~S 4rS When cðXÞ ¼ 12 cx2 ;

Proof. See the appendix. Prendergast (1995) similarly argues that managers delegate less responsibilities than would be efficient.14 In his work, underdelegation arises because the firm or the manager cannot capture all of the intrinsic benefits of implementing tasks (e.g., only the worker acquires skills by ‘‘learning-bydoing’’) in the face of the liquidity constraint imposed on workers. In the framework presented here, the manager underdelegates from the fear of increasing the worker’s bargaining power.

Skill substitution effect
(19) The owner-manager tends to underdelegate because the workers also capture some of the rent directly created by delegation (i.e., @wli =@r40). Let us call this the holdup effect. In the M-organization however there is an offsetting effect: an increase in a worker’s skills in response to larger responsibilities weakens his coworker’s bargaining return (i.e., @wli =@xj dxl ðrÞ=dro0). We call this the skill substitution effect, although it is now used to capture the impact of skill substitution on the firm owner’s incentive

21
to delegate decisions, whereas the term was earlier used to refer to the impact on the worker’s incentive to invest in skills. Eq. (19) implies that the distortion in the allocation of decision rights will be smaller in the M-organization unless the skill substitution effect is too large.15 We will now demonstrate that the optimal set of decision rights delegated to the workers tends to be larger in the M-organization. Proposition 5. When P(x) ¼ 1ex, rS orM . Proof. See the appendix. The role of ex post bargaining in getting this result is essential for two reasons. First, it is only under ex post bargaining that the workers with substitutable skills have greater incentive to invest in human capital. As additional delegation tends to induce a greater increase in human capital investment in the M-organization than in the S-organization, the efficient allocation of decision rights is typically more decentralized in the former than in the latter. Second, it is only under ex post bargaining that workers with substitutable skills have weaker bargaining power. Note that the owner-manager usually distorts the allocation of decision rights because she cannot capture all the rents created by the efficient allocation. This is similar to the classic holdup problem. But this underdelegation problem is much less severe in the M-organization where the owner-manager receives a larger share of the efficiency gain due to her stronger bargaining power in the M-organization. Under the assumption of identical production frontier, the M-organization gives a higher profit to the owner-manager for two reasons: (1) the owner-manager has stronger bargaining power in the M-organization (Proposition 2) and (2) the workers are better motivated to acquire skills in the M-organization (Proposition 3). More formally, Corollary 1. When P(x) ¼ 1ex, the M-organization gives the owner a higher profit ex post than the S-organization. Proof. pM ðrM ; xM ðrM ÞÞ4pM ðrS ; xM ðrS ÞÞ4pS ðrS ; xM ðrS ÞÞ4pS ðrS ; xS ðrS ÞÞ where the first inequality is derived by the fact that rM , is the optimal choice in the M-organization, the second is immediate from Proposition 2 and the third from Proposition 3. It is not clear whether workers’ wages will be higher or lower in the M-organization even with the same assumptions as in Corollary 1. Although
22

the workers are given more responsibilities and are more motivated to invest in firm-specific human capital, which strengthens their bargaining power, they may not receive a higher wage, simply because their share of the rent is smaller in the M-organization (Proposition 2).
COLLECTIVE BARGAINING AND COOPERATION Suppose the workers collectively negotiate their wages by forming a union and thus receive an equal union wage. Horn and Wolinsky (1988) and Stole and Zwiebel (1996b) find that workers bargaining with an indispensable firm gain by forming a union when they are substitutable to one another and lose when they are complementary.16 We restate their result without the proof. The total union wage is defined as the Nash bargaining solution between the owner-manager and the workers, as is assumed in the earlier works. Proposition 6. (Horn & Wolinsky, 1988; Stole & Zwiebel, 1996b) Given the fixed investment by the workers, collective bargaining increases the workers’ wages in the M-organization, while the workers in the S-organization do not benefit from collective bargaining. With collective bargaining, the workers’ share of the rent created by their skills is always half, regardless of the organizational form. In contrast, the workers’ share of the rent obtained through individual bargaining is higher in the S-organization, where the share is half, than in the M-organization, where the share is less than half.17 As you can easily see, collective bargaining reduces the workers’ skill investment because it encourages free-riding. Lower-skill investment also decreases the benefit of delegation for the owner-manager. Hence, the following proposition is straightforward, and thus, the proof is omitted. Proposition 7. Collective bargaining gives a lower incentive to acquire skills and induces the allocation of fewer decision rights to the workers in both organizations. As the workers in the S-organization will be worse off by forming a union, I will focus on the M-organization for now. So far, we have assumed that the workers choose their investment in skills noncooperatively even when they are unionized. When the workers work in teams, they may be able to cooperate (or collude) in choosing their investment level if each worker’s investment is observable to the other. When the workers cooperate, they

jointly optimize their total payoff: w1(x1, x2) þ w2(x1, x2) c(x1) c(x2). We consider the four possible cases: (UC) form a union and cooperate in investment; (NC) not form a union but cooperate in investment; (UN) form a union but not cooperate in investment; and (NN) not form a union and NC UN NN not cooperate in investment. Let xUC M , xM , xM ; and xM be the workers’ skill investments in each of the abovementioned cases. Proposition 8. The workers’ cooperation in setting their investment in skills benefits the owner-manager under collective bargaining but hurts the firm’s profit under individual bargaining. UC xNN M 4xM 4 max

Proof. See the appendix. Cooperation is beneficial under collective bargaining because it eliminates free-riding. Under individual bargaining, however, cooperation and autonomy in setting skill standards in the M-organization could substantially reduce efficiency. This is because the strategic substitutability of workers’ investments creates negative externality on their utilities, and internalizing this externality while neglecting the positive externality on the ownermanager’s payoff could cause significant underinvestment in skills. This cooperation in skill investment is less likely if there are many teams competing with one another. Also, frequent job rotation among teams working on similar tasks should alleviate this problem because the possibility of moving to another team, or of a worker from another team coming to your team, reduces the incentive to collude. This may partly explain why many Japanese firms have adopted job rotation.
DISCUSSION When the two organizational forms generate the same production frontier, the firm should choose the M-organization because it induces higher investment and gives the owner-manager stronger bargaining power. The M-organization is also more efficient unless it induces sufficiently excessive investment, which is very unlikely in a team with more than two workers and with sufficiently costly investment. This benefit of multiskilling practices has never been recognized in the literature. If there exist gains from
24
HIDEO OWAN k
specialization as we normally expect (e.g., pðxÞ ¼ 1 ex for kW1 in our model), the manager has to make trade-offs between the incentive efficiency from multiskilling and the technical efficiency from specialization. Eventually, the efficient job design should prevail.18 The difference between the two types of job design becomes remarkable with individual bargaining but not with collective bargaining. Therefore, the M-organization will be favored in workplaces that are not unionized and in those where there is more differentiation in wages based on skill levels. One legitimate critique to our theory may be that in many industries and occupations, especially manufacturing plants, wage bargaining is highly centralized, or a wage formula is typically standardized, even if the plant is not unionized, so that individual bargaining or the Shapley value as the wage bargaining outcome is not realistic. Our reaction to this critique is twofold. First, wages in our model should be interpreted as the lifetime wage income rather than as short-term wages. Even if workers cannot directly bargain over wages in the short run, those with better skills may influence the managers’ decisions, which affect their income in the long run (e.g., promotion, job assignment, and training). Therefore, the bargaining process formalized in our model captures a worker’s ability to make his supervisors’ decisions reflect his voice over a long period of time. Second, although our study was first motivated by a recent trend for reorganization toward job enlargement, the application of the framework should not be restricted to the work organization of lower-level workers. For example, the model may be more suitable to explain differences in job design across hierarchical levels. Pay for managers are determined by individual bargaining, much broader cross-functional knowledge/skills are required of managers, and much more decision authority is assigned to managers. Our theory may predict that job design consisting of skill requirement and decision authority assignment should be much closer to the efficient one for managers than for lower-level positions. The model may be also applicable to a comparison among different organizational forms where the relationship between human capital in different units varies. For example, compare M-form and U-form organizations. It may be the case that firm-specific human capital across functional units in the U-form organizations are complementary, whereas those across business units in the M-organizations are substitutes if there is a lot of duplication of practices among the units. Then, the model predicts that human capital investment is larger and decision-making is more decentralized in the M-form than in the U-form organizations.
Specialization, Multiskilling, and Allocation of Decision Rights
25
CONCLUSION This work makes an important contribution in two areas. First, it offers another rationale for multiskilling practices increasingly observed in industries worldwide. Multiskilling can reduce the distortion in investment and the allocation of responsibilities created by the holdup problem because multiskilling makes ‘‘bargaining returns’’ more sensitive to skill acquisition and also mitigates the manager’s fear of giving away too much bargaining power to the workers. Therefore, choosing multiskilling practices will enhance productivity unless specialization offers a substantial technical advantage. This idea that multiskilling practices mitigate the distortion in human capital investment and delegation decisions has never been discussed in the literature. Second, we have demonstrated that the multiskilling form of organization could arise as the optimal form even if there are no technological or informational task complementarities among the combined skills. Prior works typically argued that task complementarities are primary reason for many firms adopting multiskilling practices (e.g., see Lindbeck & Snower, 2000).
NOTES 1. Other terms such as cross-training, multitasking, job enrichment, and job enlargement are similarly used in the literature. Although these words have slightly different meanings, they are used almost interchangeably to describe a recent trend in job design toward a broader set of tasks and responsibilities assigned and a broader set of skills required for an individual job. 2. The way complementarity among tasks determines the degree of specialization has been discussed by authors in the job assignment literature. See Roy (1950), MacDonald (1982), and Rosen (1982) for example. 3. The emphasis on broad skills and decentralization of responsibilities in large Japanese firms have been also noted by other authors, including Cole (1979), Aoki (1988), Lincoln and Kalleberg (1990), and Kagono, Nonaka, Sakakibara, and Okumura, (1985). 4. See, for example, Arthur (1994), Dunlop and Weil (1996), MacDuffie (1995), Ichniowski, Shaw, and Prennushi (1997), Cappelli and Neumark (2001), Hamilton, Nickerson, and Owan (2003), Boning, Ichniowski, and Shaw (2007), Black and Lynch (2001, 2004), Bartel (2004), Kato and Morishima (2002), DeVaro (2006), Eriksson (2003), Bayo-Moriones et al. (2003), and Zwick (2004). 5. One analogy is Bertrand versus Cournot competition. In the former, the sale (wage) is more sensitive to price cuts (human capital investments), but the profit margin (wage level) is lower. 6. The work by Rajan and Zingales (2001) is also relevant to our research. Their work considers the effects of potential market ‘‘competition’’ between individuals
26
HIDEO OWAN
with substitutable human capital on organizational choice, whereas our analysis looks at the effects of within-firm ‘‘competition’’ among individuals with substitutable human capital. 7. For a more general n worker case, see Owan (1999). 8. Assumption 1 does not ensure that either the S-organization or the Morganization is an efficient form of skill investment. Therefore, it is quite possible that an efficient form is one in which both workers invest in both types of skills, but differentiate their investments in the two types of skills. We need more restrictive conditions to derive the result that either the S-organization or the M-organization is efficient. 9. More formally, the Shapley value is defined as follows:
wi ðXÞ ¼
1 X jSj!ðjNj jSj 1Þ!½YðS [ fig; XÞ YðS; XÞ jNj! SN\fig
where N is the set of all agents including the owner and the workers, S is an arbitrary subset, and Y(S, X) is the expected output by the subgroup S given the investment profile X. 10. It may be often more realistic to assume Edgeworth complementarity between x1 and x2 in the S-organization. Most qualitative results in this chapter hold for such a case. See Owan (1999) for discussions. 11. As we made clear earlier, the current assumptions do not ensure that either the S-organization or the M-organization is efficient. Thus, we mean constrained efficiency here: no deviation from the specified investment profile gives a better payoff to anyone without negatively affecting others within the set of investment profiles called the S-organization or the M-organization. 12. For example, suppose cðxi;1 ; xi;2 Þ ¼ 1=2cðxi;1 þ xi;2 Þ2 . Then, the workers overinvest when the cost parameter c is sufficiently small. The necessary and sufficient condition for this to be true is pðxM =2Þ43=4. 13. This assumption also implies the owner-manager’s ability to commit to her delegation decision. As ‘‘worker empowerment’’ encourages workers’ skill investment, the owner-manager may promise to delegate large amounts of authority to the workers to motivate them and then take back some of the decision rights to extract more surplus. This assumption rules out such possible reneging by the ownermanager. 14. Freeman and Lazear derive a similar result in a different context where the firm decides whether it should create a works council to empower workers or not. They argue that even if setting up a works council is efficient, the employer may not be better off by doing so because the empowered workers will likely capture a significant part of the efficiency gain. 15. There may be some pairs of production functions and cost functions that induce overdelegation in the M-organization, although we have not found any such simple functions. Overdelegation may arise if a greater allocation of decision rights increases the substitutability of the workers’ skills so significantly that further delegation weakens the workers’ relative bargaining power. 16. Segal (2003) shows a very general result to this effect concerning the desirability of coalitions under the random-order value, which gives each player his
Specialization, Multiskilling, and Allocation of Decision Rights
27
expected marginal contribution to the set of preceding players in various orderings of players, according to some probability distribution over orderings. The randomorder value in which all orderings are equally likely is the Shapley value. 17. This result may be consistent with the fact that enterprise unions are rare in the United States, where traditional firms have maintained a specialized job structure. A typical union’s goal of increasing the workers’ bargaining power probably necessitated the use of monopoly power in the industry-wide labor market. On the contrary, in Japan, where large firms have adopted many multiskilling practices, most unions are enterprise unions. 18. Suppose the owner-manager can commit to a job design at the time of hiring. Then, by adopting the efficient job design, the owner-manager should be able to make the largest profit if she only needs to guarantee young unskilled workers their reservation utility by offering an appropriate upfront wage (i.e., the reservation wage minus the ex post bargaining surplus), or the owner-manager should be able to offer the highest wage if firms compete for workers in the labor market.

Similarly, assuming m=6P0 ðxi;1 Þð3 2Pðxj;1 ÞÞom=6P0 ðxj;1 Þð3 2Pðxi;1 ÞÞ leads to contradiction. Therefore, m=6P0 ðxi;1 Þð3 2Pðxj;1 ÞÞ ¼ m=6m=6P0 ðxj;1 Þð3 2Pðxi;1 ÞÞ. Then m=6P0 ðxi;2 Þð3 2Pðxj;2 ÞÞ ¼ m=6P0 ðxj;2 Þð3 2Pðxi;2 ÞÞ from (A.1) and Assumption 1 implies xi;1 ¼ xj;1 and xi;2 ¼ xj;2 . If xi;1 ¼ xj;1 oxi;2 ¼ xj;2 , m=6P0 ðxi;1 Þð3 2Pðxj;1 ÞÞ4 m=6 P0 ðxi;2 Þð3 2Pðxj;2 ÞÞ contradicting Eq. (A.1). Hence, xi;1 ¼ xj;1 ¼ xi;2 ¼ xj;2 . It is easily seen that there exists the unique interior solution for Eq. A.1 from Assumption 3 and the concavity of the objective function.

If m=6 P0 ðxi;2 Þð3 2Pðxj;2 ÞÞ4m=6 P0 ðxj;2 Þð3 2Pðxi;2 ÞÞ, Assumption 1 suggests xi;2 oxj;2 . But Eq. (A.2) also indicates c0 ðxi;2 Þ4c0 ðxj;1 þ xj;2 Þ contradicting xi;2 oxj;2 . Thus, m=6P0 ðxi;2 Þð3 2Pðxj;2 ÞÞ m=6 P0 ðxj;2 Þð3 2Pðxi;2 ÞÞ. If xj;1 40, this combined with Eq. (A.2) implies m=6 P0 ð0Þð3 2Pðxj;1 ÞÞ

m=6 P0 ðxj;1 Þð3 2Pð0ÞÞ, which suggests xj;1 ¼ 0 from Assumption 1. As m=6 P0 ð0Þð3 2Pð0ÞÞ4m=6 P0 ðxÞð3 2PðxÞÞ for any x, this result contradicts Eq. (A.2).

But this case is ruled out by Assumption 2.

THE EFFECT OF MULTISKILLING ON LABOR PRODUCTIVITY, PRODUCT QUALITY, AND FINANCIAL PERFORMANCE Martin Farnham and Emma Hutchinson ABSTRACT A substantial literature examines the effect of high-performance workplace practices on various outcomes for firms and workers. However, little attention has been paid to the effect of broad job design on product quality or financial performance. And with rare exception, the empirical literature on outcomes from high-performance work practices treats those practices as exogenously determined. This chapter seeks to address these two shortcomings in the existing literature. Using a nationally representative cross-section of British employers in 2004, we measure the effect of multiskilling on establishment-level labor productivity, product quality, and financial performance. We find that treating multiskilling as an endogenous choice of employers in empirical models of organizational performance has significant implications for the results. In particular, the estimated (positive) effect of multiskilling on labor productivity vanishes when we treat multiskilling as an endogenous choice of employers. Treating multiskilling as an endogenous choice changes its estimated

INTRODUCTION Over the past three decades, researchers in business, sociology, and economics have investigated the causes and consequences of various ‘‘high-performance work practices’’ among manufacturers. Many such practices arose in Japanese manufacturing and were adopted by Western manufacturers beginning in the 1980s. Multiskilling – training workers to perform a variety of tasks – is one of these practices. In this chapter, we investigate the effect of multiskilling on organizational performance, as measured by labor productivity, product quality, and financial performance. In an important departure from the existing empirical literature on high-performance workplace practices and their effects on organizational outcomes, we treat multiskilling as an endogenously chosen variable in our analysis. We show that treating the choice to multiskill workers as endogenous rather than exogenous substantially changes the empirical estimates we obtain. Our findings, on their own, provide a useful contribution to the literature on the effects of multiskilling. Very little empirical work has been done to date on the effects of multiskilling (or even broad job design more generally) on organizational performance. However, our findings also have broader implications for the study of other high-performance work practices (e.g., teamwork, quality circles, total quality management, multitasking, and job rotation). The vast majority of the empirical literature on the effects of highperformance work practices treats workplace practices as exogenously determined. Our findings, therefore, suggest the need for a more careful empirical approach in this large, broader literature. Multiskilling is an element of ‘‘broad job design,’’ a common feature of modern human resource practice. Broad job design includes multitasking – where employees perform multiple tasks throughout their work shift rather than specializing in one task and job rotation – where employees perform one task or set of tasks for a period of time, then switch to another task or

set of tasks for a period of time. Because multiskilling (knowing how to do multiple tasks) is both a prerequisite to and a consequence of multitasking and job rotation, multiskilling is an integral feature of broad job design. The effect of multiskilling on organizational performance is of interest for several reasons. Over the past two decades, firms have spent billions of dollars reengineering their organizational practices to improve efficiency and, ultimately, profitability. Therefore, understanding the effect of practices such as multiskilling is clearly of interest to business. It is also of interest to designers of job training programs, who must decide whether to specialize or multiskill their trainees in preparation for reentry into the work force. Furthermore, the effects of multiskilling are of interest to those who design educational curricula. Some national educational systems value specialization, often at an early age, whereas others value broader training. If multiskilling is shown to have beneficial effects for business, this may induce educational systems to place greater emphasis on preparing their students for careers in a multiskilled workforce. We study the effect of multiskilling on firm performance using the 2004 British Workplace Employment Relations Survey (WERS). The 2004 WERS is a nationally representative cross-section of establishments including both manufacturers and nonmanufacturers. We measure the effect of multiskilling on firm performance using two basic approaches. In the first approach, we estimate three different single-equation probit models with multiskilling on the right-hand side, using as dependent variables measures of labor productivity, product quality, and financial performance of the establishment relative to its industry. Because multiskilling is a choice made by employers, this approach – which assumes multiskilling is exogenously determined – is likely to produce estimates subject to selectivity bias. Providing evidence in support of this concern, Nickell, Nicolitsas, and Patterson (2001) use British data to show that poorly performing firms are more likely to reform workplace practices than are high-performing firms. This suggests that estimates of the effect of multiskilling on our organizational performance outcomes are likely to be negatively biased. Although the possibility of selectivity bias is largely ignored in the existing empirical literature on workplace practices, another potential source of bias comes in the form of time-invariant unobserved heterogeneity that is correlated with workplace practices and affects organizational performance. For example, suppose that multiskilling is more easily adopted with a more educated workforce. Such a workforce may also be more productive. Failure to control for human capital levels of the workforce could therefore lead to upward bias in estimates of the effect of multiskilling on labor productivity.

MARTIN FARNHAM AND EMMA HUTCHINSON
A third potential source of bias is the fact that organizations adopting innovative work practices may be engaged in other, unobserved, activities that enhance performance. In this case, one would expect estimates of the effects of multiskilling to be positively biased. Finally, a fourth potential source of bias is error in measures of organizational performance that is correlated with workplace practice. These different sources of endogeneity could collectively introduce bias of unknown sign into estimates generated under the assumption of exogeneity of workplace practices. Therefore, in our second approach to estimating the effect of multiskilling on organizational performance, we explicitly address the endogeneity of multiskilling by estimating a bivariate probit for each measure of performance and by treating multiskilling as an endogenous right-hand side variable in the organizational performance equations. In each of the bivariate probit models, the multiskilling equation includes an exogenous variable that reflects volatility in the product market and is excluded from the performance equation. DeVaro and Farnham (2011) demonstrate theoretically and empirically why product market volatility is a determinant of an employer’s decision to multiskill its workers. It should be noted that, while this exclusion restriction is a source of identification in our bivariate probit models, identification does not hinge on this assumption. This is because, in our specifications, the bivariate probit is identified without an exclusion restriction. In the absence of an exclusion restriction, identification comes from the nonlinearity of the bivariate probit. When we treat multiskilling as exogenous, we find that multiskilling is associated with higher labor productivity and higher financial performance but is unrelated to product quality. When we treat multiskilling as endogenous, our results change. In this case, we find that multiskilling is unrelated to labor productivity – a finding at odds with much of the current literature on broad job design – but is associated with higher financial performance and higher product quality. Many high-performance workplace practices that were introduced in manufacturing have been adopted by firms outside the manufacturing sector. Yet, the empirical literature on the effect of workplace practices has been slow to shift its focus from manufacturing. Therefore, this study, through its use of a nationally representative sample of all establishments, serves a further useful purpose in helping to extend the empirical job design literature to focus on workplace practices among nonmanufacturing firms, which make up the vast majority of economic activity in Western economies.

Effect of Multiskilling
LITERATURE REVIEW A number of studies seek to explain the rise of broad job design over recent decades. Lindbeck and Snower (2000) describe the transition of manufacturers from ‘‘Tayloristic’’ to ‘‘holistic’’ organizations, with Tayloristic firms characterized by high levels of specialization and repetition by workers and holistic firms characterized by job rotation, integration of tasks, and learning across tasks. Lindbeck and Snower argue that the shift to multitask learning, led by Japanese manufacturers, has resulted from the rise of computers and information systems, increased flexibility of the capital stock, the growth of human capital per worker, and changes in worker tastes in favor of a more varied work experience. Boucekkine and Crifo (2008) extend the model to a dynamic framework and endogenize worker skills. Several studies address the impact of multiskilling on worker incentives. Owan (2011) argues that multiskilling creates task overlap and makes worker skills substitutable, thus creating competition among workers and providing them an incentive to acquire firm-specific human capital. Carmichael and MacLeod (1993) write that multiskilled workers may have greater incentives than specialized workers to reveal hidden information about the optimal implementation of technological change in the firm’s production process. Cosgel and Miceli (1999) argue that multiskilling enhances peer monitoring (Kandel & Lazear, 1992) by giving workers information about each other’s jobs. Other studies highlight the role of learning by workers and employers that results from broad job design. Ortega (2001) and Eriksson and Ortega (2006) argue that employers who face imperfect information use job rotation to learn which workers are best at which tasks. This allows for more profitable matching of workers to positions. A different set of studies note that multiskilled workers are essential to process improvement. Koike (1985) and Aoki (1986) note that multiskilled workers are better than specialists at dealing with emergent events (such as equipment breakdown) on the production line. Wang (2002) argues that multiskilling aids coordination of workers. Morita (2005) and Gibbs, Levenson, and Zoghi (2010) argue that workers with a broad understanding of production can better suggest improvements. Although much of the literature on broad job design has focused on its role in facilitating process innovation, DeVaro and Farnham (2011) argue that specialized workers are better than multiskilled workers at product innovation. They model a multiproduct firm that can train workers to produce multiple products or specialize workers in a single product. In the
40
MARTIN FARNHAM AND EMMA HUTCHINSON
model, benefits of multiskilling come in the form of increased flexibility in labor allocation that allows resources to be quickly shifted from less profitable to more profitable goods in the firm’s product line. Costs of multiskilling come in the form of a diminished ability to alter a good to meet shifting consumer demand due to broad but shallow training. More volatility in the product market means firms need to innovate more to produce goods that meet the current specifications demanded by consumers. DeVaro and Farnham’s model predicts that greater product market volatility will lead to greater specialization of workers. Using data from the 2004 British WERS, they corroborate their theoretical prediction with empirical results that increased product market volatility leads to less multiskilling. Their finding forms the basis for the exclusion restriction used in this chapter and discussed further in the section on Empirical Strategy and Analysis. One of the empirical questions we address in this chapter is the relationship between multiskilling and labor productivity. Of the abovementioned theoretical studies, several imply a positive effect of broad job design on labor productivity through improved incentives, better matching, or better understanding of the production process. On the contrary, economists since Adam Smith (1776) have pointed to productivity gains from specialization. Therefore, theoretical claims about the effect of multiskilling on labor productivity are mixed and arguably the sign of this effect remains an empirical question. Ichniowski, Shaw, and Prennushi (1997) use longitudinal data on steel finishing lines to measure the effect of human resource management systems and individual workplace practices on plant performance. In fixed effects models including only job rotation as the work practice of interest, they find job rotation to be positively associated with productivity. However, when they include controls for human resource management systems, the coefficient on job rotation becomes negative. Cappelli and Neumark (2001) use longitudinal US data from the National Employers Survey and the Longitudinal Research Database to investigate the effect of high-performance work practices on labor productivity and labor costs. Under the assumption that no high-performance work practices were in place in 1977, they find that while high-performance practices as a group generally raise labor productivity, job rotation tends to be associated with lower labor productivity. Although these studies control for unobserved time-invariant heterogeneity by use of fixed effects methods, neither of them addresses the potential selectivity bias resulting from the fact that job design is an endogenous choice of managers and neither directly addresses the effect of multiskilling on labor productivity.
Effect of Multiskilling

The only study of broad job design that treats workplace practice as an endogenous choice of managers is Zwick (2002). He treats continuous job training as endogenous and includes job rotation on the right-hand side in his model. He does not directly address the endogeneity of job rotation, however. Zwick finds no effect of job rotation on firm productivity, using a panel of German firms. A number of more general studies of high-performance work practices address the effect of bundles of practices on labor productivity. Most find high-performance work practices to be positively related to labor productivity (Caroli & Van Reenen, 2001; Huselid, 1995; Ichniowski et al., 1997). Black and Lynch (2001, 2004) find that only certain combinations of such practices are associated with higher productivity. Huselid and Becker (1996) find no effect of such practices on labor productivity once controlling for unobserved firm-level heterogeneity. Another empirical question we address is the effect of multiskilling on product quality. Osterman (1994) argues that firms pursuing ‘‘high road’’ practices such as offering high-quality products are more likely to engage in high-performance work practices. Wang (2002) directly addresses multiskilling when he assumes that multiskilling will increase product quality by increasing coordination between work groups and reducing production errors. Morita (2005) also suggests that product quality will benefit from multiskilling of workers due to its contribution to the improved functioning of quality circles. To our knowledge, no empirical study has addressed the impact of multiskilling (or even broad job design) on product quality. Although Ichniowski et al. (1997) find that bundles of high-performance work practices are associated with higher product quality, they do not specifically address the empirical relationship between product quality and broad job design. Many of the theoretical papers mentioned earlier also have implications for the effect of multiskilling on financial performance. Ceteris paribus, increases to labor productivity or product quality should lead to greater revenues and hence greater profits for a firm. However, multiskilling may also result in higher training costs. And multiskilling could affect firm financial performance through other channels such as the removal of layers of management. Although economists generally assume firms engage in activities that contribute to profit maximization, it remains possible that some persistent management trends are counterproductive. Although Huselid (1995) and Huselid and Becker (1996) discuss effects on financial performance, they draw inference from data on labor costs and labor productivity, rather than data on profits or other measures of overall
42
MARTIN FARNHAM AND EMMA HUTCHINSON
financial performance. To our knowledge, the specific relationship between multiskilling and financial performance has not been previously studied. Importantly, only one of the aforementioned empirical studies (Zwick, 2002) treats work practices as an endogenous choice of organizations and therefore addresses selectivity bias. DeVaro (2008) provides a list of 24 articles on the effects of workplace practices on firm and worker outcomes, all but one of which treat workplace practices as exogenously determined.1 Although several studies use panel data to control for time-invariant unobserved heterogeneity at the firm or establishment level (e.g., Black & Lynch, 2001, 2004; Cappelli & Neumark, 2001; Caroli & Van Reenen, 2001; Huselid & Becker, 1996; Ichniowski et al., 1997), such fixed effects approaches cannot control for time-varying heterogeneity, which is likely to underlie the differential choice of organizations whether or not to engage in practices like multiskilling. Without controlling for selection into treatment, these studies risk providing biased estimates of the effect of the treatment on organizational performance. Our study contributes to the literature on job design and highperformance work practices in the following ways. Ours is the first paper, to our knowledge, to investigate the effect of multiskilling on product quality or financial performance. Perhaps more importantly, we treat multiskilling as an endogenous choice of organizations and show that addressing potential selectivity bias makes a difference in the estimates we obtain. This allows us to make a new contribution to the small literature on broad job design and labor productivity. Furthermore, it illustrates that in the broader literature on the effects of workplace practices – including practices and outcomes not included in our study2 – there is reason to treat the endogenous choice of workplace practices carefully. Our paper also contributes usefully to the literature by employing a nationally representative sample of establishments from both manufacturing and nonmanufacturing sectors. Therefore, the results we present come not from a single firm, industry, or sector, but from the British economy as a whole and are hence more likely to be generalizable than results of more narrow studies.
DATA Our data source is the management questionnaire from the 2004 British WERS, jointly sponsored by the Department of Trade and Industry, the Advisory, Conciliation and Arbitration Service, the Economic and Social Research Council, and the Policy Studies Institute. Distributed through the
43

UK Data Archive in November 2005, the WERS data are a nationally representative stratified random sample covering British workplaces with at least five to nine employees, except for local units in Northern Ireland and those in the following 2003 Standard Industrial Classification (SIC) divisions: agriculture, hunting, and forestry; fishing; mining and quarrying; private households with employed persons; and extraterritorial organizations. The 2004 WERS was the fifth such survey, following earlier waves in 1980, 1984, 1990, and 1998. The sampling frame used for WERS 2004 is the Inter-Departmental Business Register (IDBR), which is maintained by the Office for National Statistics (ONS). As noted by Chaplin, Mangla, Purdon, and Airey (2005), ‘‘The IDBR is undoubtedly the highest quality sample frame of organisations and establishments in Britain. The frame is continuously up-dated from [administrative tax] records and establishments that no longer exist are removed reasonably quickly.’’ Our measure of multiskilling is based on the answer to the following question: ‘‘Approximately, what proportion of [workers in the establishment’s largest occupational group] are formally trained to be able to do jobs other than their own?’’ From this, we define the following binary response variable: Multiskilling ¼ 1 if the proportion is positive ¼ 0 if the proportion is zero The respondent for each establishment in the WERS is asked how (1) the current labor productivity of the establishment; (2) the current product quality of the establishment; and (3) the current financial performance of the establishment compare with other establishments in the same industry. In answering each question, respondents can choose between ‘‘A lot better than average,’’ ‘‘Better than average,’’ ‘‘About average for industry,’’ ‘‘Below average,’’ ‘‘A lot below average,’’ and ‘‘No comparison possible.’’ On the basis of these responses, we construct three binary measures of organizational performance as dependent variables in our statistical models: Labor Productivity, Product Quality, and Financial Performance. Each of these variables equals 1 if the establishment’s current performance relative to that of other establishments in the industry is reported to be above average and 0 if it is reported to be at or below average. The survey also includes a question about how the respondent interprets the term ‘‘financial performance,’’ with possible responses including profit, costs, sales, value added, and so on. We show that restricting the sample for the financial performance models to those employers interpreting the
44
MARTIN FARNHAM AND EMMA HUTCHINSON
variable to mean ‘‘profit’’ makes little difference in the estimates obtained. Therefore, we use the full sample for most of our analysis. One potential criticism of our methodology is the fact that we use a dataset with subjective performance measures. In defense of these measures, the WERS is an anonymous survey and so respondents do not have strong incentives to give misleading answers. Reporting errors may be a problem, although the respondent is typically a senior manager at the establishment and therefore is presumably well informed about the performance of the establishment relative to the industry. And, as evidenced by recent accounting scandals, reporting problems can also occur with objective measures of organizational performance such as accounting profits. There is evidence suggestive of systematic reporting errors in the subjective performance measures, as seen by the fact that more than half of respondents report their establishment is doing better than the industry average (Table 1). The skewness of the distribution of performance outcomes becomes more apparent when you consider that the percentage of respondents who say that their establishment is performing below the industry average is only 7%, 2%, and 8% for Labor Productivity, Product Quality, and Financial Performance, respectively. DeVaro (2008) discusses this issue. One explanation for such a skewed distribution of reported performance is that establishments existing at the time of the survey are more successful than the average establishment in the population. Unsuccessful firms tend to go out of business quickly and are therefore less likely to be captured in a survey than successful firms. Another possibility is that managers may tend to overreport performance out of a sense of pride in their work. One can interpret this as a relabeling of the categories describing organizational performance. As long as this relabeling is uncorrelated with the treatment, it poses no problem for our estimates. Of greatest concern is the possibility that some systematic reporting error is correlated with the decision to multiskill workers. For instance, more optimistic managers may tend to be more receptive to high-performance work practices while also tending to be overly bullish on the performance of the establishment.3 Because we use an estimation strategy that explicitly accounts for correlation between unobserved determinants of multiskilling and organizational performance, systematic reporting errors that are correlated with the treatment should not confound our estimates. Summary measures of descriptive statistics for all variables in the analysis are displayed in Table 1. We use establishment sampling weights when computing the statistics in this table and in all of our subsequent analyses. Table 1 displays descriptive statistics for the variables in analysis and

EMPIRICAL STRATEGY AND ANALYSIS We use and compare two basic empirical strategies in the analysis that follows. The first strategy involves estimating simple single-equation probits with a measure of organizational performance – Labor Productivity, Product Quality, or Financial Performance – as the dependent variable and Multiskilling as the key independent variable. In this approach, we assume that the dependent variable of interest is determined by an unobserved latent variable Y i ¼ X 0 i b þ MS0 i d þ ui
(1)
where i ¼ 1,y, N indexes establishments. Yi is observed and Yi ¼ 1 if the unobserved Y i 0. Yi ¼ 0 otherwise. MSi is a dummy variable indicating whether the establishment employs multiskilling in the workplace. Xi is a vector of establishment-level characteristics including measures of establishment size and age, unionization, management structure, characteristics of worker contracts, and foreign ownership status. These control variables are detailed in the appendix. We do not include industry controls, as the dependent variable is defined relative to the industry mean. ui is an error term, which we assume to be iid normal. Given this assumption, our data are described by a probit model, PrðY i ¼ 1Þ ¼ FðMS0 i d þ X 0 i bÞ where F denotes the cumulative normal distribution function.

Effect of Multiskilling
Underlying this specification is the implicit assumption that Multiskilling is exogenously determined. This approach is consistent with the vast majority of the existing literature on workplace practices. Results obtained from this approach are given in Table 2. Given that Multiskilling is an establishment-level choice, and therefore may be correlated with the error term, our second, and preferred, empirical strategy treats this variable as endogenously determined. We do this by estimating bivariate probits with Multiskilling and one of our three organizational performance variables treated as the two endogenous variables. As in Eq. (1), we assume that Multiskilling is determined by an unobserved latent variable, MSi ¼ V 0i p þ X 0 i g þ vi
(3)
where the observed MSi is equal to 1 if MSi 0 and is equal to 0 otherwise. Again, i indexes establishments, and Xi is the same vector of establishment-level characteristics as in Eq. (1). Vi denotes an exogenous determinant of Multiskilling described later. We assume that ui and vi are jointly normally distributed with mean zero and variance one, and we let r ¼ Corr(ui, vi). Recent work by DeVaro and Farnham (2011) shows theoretically and empirically why volatility in the product market is a determinant of an employer’s decision to multiskill its workers. Following that analysis, we define a binary measure of product market volatility. Volatility ¼ 1 if the current state of the market for the main product or service of the establishment is described as ‘‘turbulent’’ (¼ 0 otherwise).5 To aid in identification, we include in Eq. (3) the exogenous dummy variable, V, denoting Volatility. V is excluded from the organizational performance equation (Eq. (1)). Excluding Volatility from the organizational performance equation is appropriate if Volatility only affects performance through the Multiskilling variable. This is arguably a reasonable assumption. Although product market volatility is likely to affect the variance of labor productivity, product quality, and financial performance, it does not seem likely to affect the mean of any of these measures of organizational performance. For example, in an industry with high product market volatility, the probability of consumers demanding a product that is very easy to make or very hard to make will be higher than in an industry with low volatility. But the mean of labor productivity should not vary with product market volatility. This is

especially true given that our organizational performance measures are defined relative to the industry mean. One might argue that attrition will be higher in industries with greater product market volatility, as a result of higher variance in financial performance. If survey respondents do not take this attrition into account when stating how their organization performs relative to the industry, this could lead to firms in high-volatility industries reporting higher mean values of organizational performance relative to the industry mean than those in low-volatility industries. One might expect, however, that survey respondents would be familiar enough with their industry to take attrition into account when reporting on organizational performance relative to the industry mean. Even if one takes issue with the validity of our exclusion restriction, identification does not hinge on this assumption. In contrast to the linear simultaneous equations model, the parameters in the bivariate probit model with a dummy endogenous variable on the right-hand side are identified (except in unusual cases, such as one demonstrated in Maddala 1983, that do not apply here) even in the absence of exclusion restrictions (Heckman, 1978; Monfardini & Radice, 2008; Wilde, 2000). Identification comes from the nonlinearity of the bivariate probit. Given that the model can be estimated with and without the exclusion restriction, we are able to test the restriction. Following DeVaro and Farnham (2011), we restrict our analysis to multiproduct establishments. Both the theory and the empirical evidence in DeVaro and Farnham (2011) suggest restricting the sample to multiproduct establishments.6 In Table 2, we report estimation results from single-equation probit models using as dependent variables Labor Productivity (column 1), Product Quality (column 2), and Financial Performance (column 3). This approach, in which Multiskilling is treated as exogenous, is standard in the literature. Focusing on results that are statistically significant at the 5% level using two-tailed tests, the main result from Table 2 is that, ceteris paribus, multiskilling is positively associated with both labor productivity and financial performance but not product quality. The magnitudes of the effects in the labor productivity and financial performance models are similar and substantial. In both cases, the incremental effect of changing Multiskilling from zero to one on the probability that the dependent variable equals 1 is about 0.2, which amounts to a 35–40% increase in the probability that the establishment is performing above the industry average for those outcomes.7

Tables 3 and 4 display the main results of our chapter. We report the results of bivariate probit estimation for the labor productivity model (Table 3, columns 1 and 2), the product quality model (Table 3, columns 3 and 4), and the financial performance model (Table 4, columns 1 and 2). In each of the three models, Multiskilling appears as an endogenous right-hand side variable in the equation for organizational performance, and the crossequation error correlation, r, is treated as a free parameter. The bivariate probit results given in Tables 3 and 4 differ markedly from the single-equation probit results of Table 2. In the bivariate labor productivity model (Table 3, columns 1–2), the estimated effect of Multiskilling is now statistically insignificant, in contrast to the singleequation probit model of Table 2 where it was positive and significant. And in the product quality model (Table 3, columns 3–4), the estimated effect is now positive and significant, in contrast to the single-equation probit model of Table 2 where it was insignificant. Only for financial performance is the qualitative result the same between the two tables, namely that multiskilling is associated with an increased probability of high financial performance. And even in this case, the magnitude of the mean incremental effect of changing Multiskilling from 0 to 1 is nearly three times what it was in the single-equation specification. The Volatility coefficient in the Multiskilling equation is estimated with low precision; in the financial performance model, it is statistically insignificant, and in the labor productivity and product quality models, it is significant only at the 10% level and 5% level, respectively, for one-tailed tests. Another result of interest from Tables 3 and 4 concerns the estimated value of r, the cross-equation disturbance correlation. For both the product quality and the financial performance models, r is negative, large in magnitude, and estimated with high precision. For the labor productivity model, r is 0.43 but statistically insignificant. An important result that can be seen by comparing Table 2 (where r ¼ 0 is implicitly imposed) and Tables 3 and 4 (where r is a free parameter to be estimated) is that the endogeneity of Multiskilling matters a lot for measuring its effect on organizational performance. The Multiskilling coefficient is highly sensitive to the value of r, and the pattern of results reveals that lower values of r are associated with higher values of the coefficient on Multiskilling. Given that r is so low in the financial performance and product quality models, the estimated coefficient of Multiskilling is large in those models, and in the case of product quality, it becomes statistically significant whereas it was insignificant when r was constrained to be zero in Table 2. Similarly, because r ¼ 0.42 in the labor productivity model, the estimated Multiskilling

coefficient is considerably smaller (i.e., negative and insignificant) compared with the corresponding coefficient in Table 2. The result that Multiskilling appears to have no effect on labor productivity in the bivariate probit should be interpreted with caution, because the parameter of primary interest (i.e., the Multiskilling coefficient) is highly sensitive to the value of r, which is estimated with very low precision in the case of labor productivity. While r ¼ 0.43, it is statistically insignificantly different from zero, and as seen in Table 2, if r ¼ 0, then Multiskilling has a clear positive association with labor productivity that is large in magnitude. The sharp differences between Tables 2 and Tables 3–4 reveal that the endogeneity of Multiskilling matters a lot, but the exclusion restriction that contributes to identification of the bivariate probit models might be questioned and merits further scrutiny. As noted earlier, the bivariate probit model is, in principle, identified even in the absence of exclusion restrictions. We reestimate the models of Table 3, including Volatility in all equations. These results (available from the authors upon request) are qualitatively identical to those we report in Tables 3–4 and quantitatively extremely similar. Furthermore, in the organizational performance equations, the Volatility coefficient is far from statistically significant (z ¼ 0.13 in the labor productivity model, z ¼ 0.24 in the product quality model, and z ¼ 0.96 in the financial performance model). In the Multiskilling equations, where the theoretical model in DeVaro and Farnham (2011) predicts a negative effect of volatility, precision is modest; yet, the Volatility coefficient is in all cases statistically significant at the 10% level using one-tailed tests. In summary, the statistical results are supportive of the exclusion of Volatility from the organizational performance models, and in any event, our main results do not hinge on this identifying assumption and hold even in its absence. Our results concerning financial performance are of particular interest, given that the literature on broad job design has tended to focus on other outcomes (e.g., labor productivity) that are intermediate to financial performance. Financial performance, or profit, is of interest because it is the broadest possible measure of organizational performance, incorporating the full spectrum of benefits and costs of multiskilling. But the term ‘‘financial performance’’ is subject to multiple interpretations, and although the modal response in the WERS data interprets the term as synonymous with profit, there are also other interpretations. For this reason, for the financial performance model, we reestimate the bivariate probit (from Table 4, columns 1–2) using the subsample of employers interpreting financial performance as synonymous with profit. The results, displayed in Table 4, columns 3–4, are qualitatively the same as those in Table 4, columns 1–2,

DISCUSSION A substantial literature exists examining the effect of high-performance workplace practices on various outcomes for firms and workers. However, little attention has been paid to the effect of broad job design on product quality or financial performance. And almost without exception, the empirical literature on outcomes from high-performance work practices has treated those practices as exogenously determined.9 This chapter seeks to address these two shortcomings in the existing literature. We estimate the effect of multiskilling on three measures of firm performance – labor productivity, product quality, and financial performance. We begin with an estimation strategy that assumes multiskilling is exogenously determined. We then estimate bivariate probits that treat multiskilling as an endogenous choice of managers. Results change qualitatively for the labor

productivity and product quality models when we treat multiskilling as endogenous. And while results for the financial performance model remain qualitatively the same as in the single-equation probit, the magnitude of the estimated effect of multiskilling is much higher when multiskilling is treated as endogenous. Tests of our identifying restriction suggest that it is valid. Results obtained without the exclusion restriction – identifying off of the nonlinear functional form – are qualitatively identical and quantitatively very similar. In labor productivity models, we find that when we treat multiskilling as exogenously determined, it has a positive and statistically significant relationship with labor productivity, but when we treat multiskilling as endogenously determined, it has no statistically significant relationship with labor productivity. These findings are consistent with bias resulting from a form of reverse causality. Broad job design is generally thought to require higher levels of human capital than is narrow job design (specializing workers). For example, Lindbeck and Snower (2000) argue that the rise of multitasking is partly attributable to rising human capital levels in the workforce. Therefore, the positive association between multiskilling and labor productivity that we find in our single-equation probit may simply result from the fact that firms with more skilled (and hence productive) workers are more likely to adopt multiskilling. It is worth noting however that our estimate of r, the correlation of the error terms in the Labor Productivity and Multiskilling models, is very imprecise. Therefore, the difference in estimates between the single-equation probit and bivariate probit should not be overemphasized in this case. Our findings on labor productivity contribute to a small literature of mixed empirical findings on broad job design and productivity. Ichniowski et al. (1997) find that job rotation raises labor productivity when other work practices are not controlled for. This finding is consistent with our estimate from the single-equation probit. They find a negative effect of job rotation on labor productivity when controlling for other work practices. Zwick (2002) finds no effect of job rotation on productivity. We find no effect of multiskilling, when controlling for endogeneity of multiskilling. As noted earlier, a more general literature that looks at the effect of bundles of work practices on labor productivity (Black & Lynch, 2001, 2004; Caroli & Van Reenen, 2001; Huselid, 1995; Ichniowski et al., 1997) tends to find positive effects. Given the imprecision with which we estimate r, it is difficult to argue that we can resolve the mixed findings in the literature. In product quality models, we find that when we treat multiskilling as exogenous, it has no statistically significant relationship with product quality, but when we treat multiskilling as endogenously chosen, it has a statistically significant positive relationship with product quality. This is

consistent with poorly performing firms adopting reforms to change course (Nickell et al., 2001). If firms with product quality problems are more likely to adopt multiskilling, this will tend to bias downward the effect of multiskilling on quality in a single-equation probit specification. In this case, the estimate of r we obtain from the bivariate probit is large in magnitude and precisely estimated, suggesting that selectivity bias is a serious problem in the product quality models. In financial performance models, we find that when we treat multiskilling as exogenously determined, it has a statistically significant positive relationship with financial performance, but when we treat multiskilling as endogenously chosen, the statistically significant positive relationship nearly triples in size. This too is consistent with Nickell et al. (2001) and the selectivity bias that we would expect to follow from those findings. The estimate of r that we obtain from the bivariate probit is large in magnitude and precisely estimated, suggesting that selectivity bias is a serious problem in the financial performance models. This is true whether we use the full analysis sample or restrict the sample to establishments whose respondent manager equates financial performance with profit. We use product market volatility as an excluded variable in the bivariate probit specifications on grounds that product market volatility should affect the choice of multiskilling (DeVaro & Farnham, 2011) but should not affect labor productivity, product quality, or financial performance. Volatility is significant at the 10% level for a one-sided test in each of the bivariate multiskilling probits. As this exclusion restriction is not required for identification, we estimate separate bivariate probits without the restriction and obtain qualitatively identical results. It is worth noting some ways in which our approach in this chapter is limited. The nature of our dataset restricts us to a cross-sectional analysis. Although the WERS has a panel component to it, the measure of product market volatility that we use as an identifying restriction is only available in the 2004 survey.10 Therefore while we are able to estimate the error correlation in the bivariate probits, we cannot ascertain anything about how this relationship has changed over time. Another shortcoming of our approach is that our use of qualitative responses in place of organizational performance measures limits, somewhat, the applicability of our findings. We cannot convert our findings into a dollar return to multiskilling, for instance. We discuss potential problems with qualitative responses in greater detail in the section on Data. The main disadvantage of our approach is that we do not analyze systems of work practices. Holmstrom and Milgrom (1994) argue that workplace

57
practices need to be analyzed together, not in isolation. Although a number of empirical studies have attempted to study workplace practices in various bundles, the empirical evidence in support of this approach is mixed. Cappelli and Neumark (2001), for instance, find little evidence of important clustering effects of workplace practices. Huselid (1995) also finds limited evidence for important clustering effects. Black and Lynch (2001) find that some combinations of workplace characteristics have important interactions, but these mostly involve whether or not the establishment is unionized. Black and Lynch (2004) argue that one is more likely to discover such synergies in intra-industry studies than in representative samples of firms, due to a greater ability to control for unobserved heterogeneity. Because there exists little theoretical direction on how to specify interactions between workplace practices, we study multiskilling in isolation. If important synergies between multiskilling and other workplace practices do exist, this could potentially bias our estimates of the effect of multiskilling on organizational outcomes. With those caveats, our approach presents some important advantages relative to the existing literature. We explicitly address the selectivity bias resulting from endogenous choice of workplace practices, which has only rarely been done in this literature. We measure relationships between multiskilling and two organizational outcomes – product quality and financial performance – that have not been previously measured in the literature. Furthermore, compared to industry studies (Ichniowski et al., 1997) or studies of the manufacturing sector (e.g., Black & Lynch, 2001, 2004), we benefit from the generalizability that comes from using a representative sample of British establishments. Manufacturers make up just 13% of the WERS, and given the increasing application of high-performance work practices in nonmanufacturing organizations, it is useful to broaden the empirical focus of this literature to include these organizations. In future work, we plan to estimate the effect of multiskilling using data with accounting measures of productivity and financial performance. Such quantitative measures of the impact of multiskilling would arguably be of greater use than the qualitative measures we obtain here. We also plan to explore the mechanism by which financial performance improves when multiskilling is employed. Our findings that multiskilling has no effect on labor productivity but is associated with higher product quality and better financial performance are plausibly consistent with each other. But it would be useful to shed more light on how multiskilling ultimately improves financial performance. Measuring effects of multiskilling on other outcomes, such as labor costs, could lend added insight.

NOTES 1. DeVaro (2006) is the exception. 2. For instance Godard (2001) and Askenazy, Caroli, and Marcus (2002) investigate the effect of workplace practices on worker well-being, rather than organizational performance. 3. DeVaro (2008). 4. In Table 1, we use all available observations for each variable to compute summary statistics. Analogous tables that compute summary statistics based on the smaller subsamples on which the multivariate statistical models are estimated closely match Table 1. 5. Other possible responses were ‘‘growing,’’ ‘‘mature,’’ or ‘‘declining.’’ 6. The model in DeVaro and Farnham is of a firm deciding whether to train workers in the production of one good or multiple goods. Thus it technically only applies to a multiproduct firm. Empirical results corroborating their theory are only found in the subsample of multiproduct firms. 7. Our data contain a categorical measure of multiskilling that denotes different degrees of multiskilling. In results not given here, we include this richer measure of multiskilling as a set of dummies on the right-hand side of our probit models. Results are quantitatively very similar and qualitatively identical to those obtained using a binary measure of multiskilling. For clarity of exposition, we choose to report results in Tables 2–4 using just the binary measure. 8. Results available upon request. 9. Zwick (2002), which treats continuous training as endogenously chosen, and DeVaro (2006) and DeVaro (2008), which treat teamwork as an endogenous choice of managers, are exceptions to this rule. 10. Huselid and Becker (1996) note that use of panel data, especially over short periods, can introduce bias from measurement error that more than outweighs the bias reduction resulting from panel methods that control for establishment-level heterogeneity.

TEAMS, AUTONOMY, AND THE FINANCIAL PERFORMANCE OF FIRMS: NEW EVIDENCE FROM PANEL DATA Jed DeVaro ABSTRACT I use the 1998–2004 Workplace Employee Relations Survey (WERS) panel data set of British establishments to analyze the effect of team production (either autonomous/self-managed or closely managed) on financial performance. The pattern of evidence is consistent with a positive association between team production in an establishment’s largest occupational group and the likelihood of improved financial performance for that establishment. However, the results are mixed concerning whether the positive effects of teams are larger for autonomous teams versus nonautonomous teams.

JED DEVARO
INTRODUCTION In earlier work, I explored the effect of team production on organizational performance (DeVaro, 2006, 2008; DeVaro & Kurtulus, 2006), using crosssectional establishment-level data from the 1998 British Workplace Employee Relations Survey (WERS). In the first of these studies (DeVaro, 2006), I analyzed the effect of team production on financial performance and whether and how this effect varied by whether the teams were selfmanaged or closely managed. The main result of the paper was that higher financial performance was indeed associated with the use of teams, although there was no evidence that self-managed (or autonomous) teams were more beneficial than closely managed teams as is commonly argued in the vast empirical literature on the effects of teams on organizational performance. The paper differed from most of the prior literature in two ways. First, it estimated empirical models in which both teams and autonomy were treated as endogenous along with financial performance. Second, its use of financial performance as the dependent variable was unusual; the prior literature has been dominated by intermediate outcome measures (e.g., labor productivity) and financial performance is rarely if ever seen. Financial performance (interpreted as synonymous with profit in the WERS sample I used) is ultimately of interest in assessing whether teams, autonomous or otherwise, are beneficial to organizations on average. This is because financial performance incorporates the full spectrum of benefits and costs associated with teams, in contrast to intermediate measures such as labor productivity. One limitation of my earlier studies is that they are based on only a single cross-section, so that all of the identifying information from the data derives from variation across employers in the nature and use of team production in a given year. The most recent wave of the WERS offers an opportunity to address this limitation, given that the 1998–2004 panel is the first WERS panel containing information on teams, autonomy, and financial performance. My goal in this chapter is to use the 1998–2004 WERS panel to reinvestigate the question of whether and how teams affect financial performance and whether and how this effect varies by whether teams are granted autonomy. The analysis exploits temporal variation in the use of teams and autonomy within production units as well as variation across production units at a point in time. I focus only on financial performance, as opposed to labor productivity and product quality that I studied in DeVaro (2008), because neither of these intermediate measures of organizational performance is included in the 1998–2004 panel. Consistent with my earlier work using the 1998 WERS cross-section, the pattern of results suggests that
Teams, Autonomy, and the Financial Performance of Firms
65
teams are associated with a greater likelihood of improved financial performance over the period studied, but the evidence regarding whether autonomous or nonautonomous teams are better is mixed and inconclusive. The remainder of the chapter is organized as follows. In the second section, I provide some background on the previous literature and the theoretical channels through which teams – autonomous or closelymanaged – can be expected to influence organizational performance. In the third section, I describe the 1998–2004 WERS panel data set on which the analysis is based. In the fourth section, I present the empirical analysis, and in the fifth section, I discuss some limitations of the analysis and then conclude with some suggestions for a program for collection of new data.
BACKGROUND AND PREVIOUS LITERATURE An economic approach to research on teams requires weighing the benefits of teams to organizational performance against the costs. It is frequently argued, in both academic and managerial circles, that the benefits of team production outweigh the costs more often than not, and that the case for teams is even stronger when they are autonomous or self-managed than when they are nonautonomous or closely managed. Teams, particularly selfmanaged ones, are frequently cited in textbook discussions of the practices for achieving high-commitment human resource management (Baron & Kreps, 1999, p. 89). A critique of the teams literature is that the costs of team production tend to receive less emphasis and attention than the benefits, particularly outside of economics. At least part of the reason why teams, and particularly self-managed teams, are thought to be beneficial derives from the dependent variables that are typically used in teams research. As discussed in Cohen and Bailey (1997), there are three broad sets of dependent variables that appear in the literature: attitudinal outcomes such as employee satisfaction, commitment, and trust in management; behavioral outcomes such as worker absenteeism, turnover, and safety; and organizational performance outcomes such as quantity and quality of outputs, efficiency, labor productivity, sales, response time, wages, customer satisfaction, innovation, and financial performance. As argued in Cohen and Bailey, when the literature as a whole is reviewed, the estimated effects of teams are generally positive when the dependent variable is either an attitudinal measure or a behavioral measure, and the positive effects are stronger for self-managed teams more often than not. However, when the dependent variable is a measure of organizational
66
JED DEVARO
performance, the evidence is less clear. Therefore, the commonly held view that teams, particularly self-managed ones, are beneficial likely arises from thinking of this literature as a whole, grouping all dependent variables, even though the picture is less clear when we focus only on organizational performance measures. All of this is to say that empirical analyses on the effects of teams, autonomous or otherwise, on organizational performance, are still of interest despite the vast literature on teams that already exists. The empirical literature on teams in economics focuses almost entirely on dependent variables that reflect organizational performance, particularly labor productivity and product quality. A summary of that literature can be found in DeVaro (2008). In some studies, teams are studied in isolation and in others as part of broader systems of high-performance work practices (Boning, Ichniowski, & Shaw 2003; DeVaro 2006, 2008; Encinosa, Gaynor, & Rebitzer, 2000; Gaynor & Gertler, 1995; Hamilton, Nickerson, & Owan 2003; Hansen, 1997; Ichniowski, Shaw, & Prennushi, 1997; Jones, Kalmi, & Kauhanen 2010; Jones & Kato, 2011; Leibowitz & Tollison, 1980; Liberti, 2003; Nalbantian & Schotter, 1997). Financial performance, as studied in this chapter in a panel context and in DeVaro (2008) in a cross-sectional context, is of particular interest as an outcome variable, given that it accounts for the full spectrum of benefits and costs associated with team production. The potential benefits of teams to organizational performance are well known, accruing through information sharing among workers and the complementarities arising when workers have knowledge that is nonduplicative and relevant to the production process (Lazear, 1995, 1998). Against the potential benefits are costs, particularly those associated with free riding (Alchian & Demsetz, 1972; Holmstrom, 1982; Itoh, 1991, 1992; Legros & Matthews, 1993; McAfee & McMillan, 1991; Rasmusen, 1987). Granting authority, either to individual workers or to teams, also is associated with benefits and costs that have been extensively explored in the theoretical literature in economics and other disciplines. One potential benefit, as discussed in the organizational behavior literature, is enhanced worker motivation (Hackman, 1987). Another rationale for autonomy derives from socio-technical systems theory (e.g., Pearce & Ravlin, 1987). This literature argues that team members jointly optimize the social and technical systems of the organization and that the whole exceeds the sum of the parts when there is ‘‘fit’’ between these systems. Another potential benefit is discussed in Batt (2001), namely, the cost savings that can arise from eliminating supervisory roles. Whether it makes sense for a firm to
Teams, Autonomy, and the Financial Performance of Firms
67
grant teams autonomy should depend in large part on which means of monitoring workers is most efficient for the production context. There is evidence that in some settings, the peer monitoring that occurs in selfmanaged teams is superior to supervisory monitoring by encouraging workers to meet the norms self-imposed by the group (Barker, 1993). The economics literature concerning delegation of authority within organizations is also relevant to a discussion of the benefits and costs of granting autonomy to teams. Delegation of authority can be thought of as conferring ownership of an asset to which the owner has decision rights regarding its use (Grossman & Hart, 1986; Hart, 1995; Hart & Moore, 1990). An idea that emerges from this literature is the notion that agents (e.g., team members) have weaker incentives to take actions that will benefit the firm if they are denied decision-making authority. Endowments of information, particularly asymmetric endowments, are key to such models. For example, Aghion and Tirole (1997) argue that a principal who has formal authority over a decision or activity can choose to reverse a subordinate’s decision but will avoid doing so if the subordinate is better informed and if their objectives are correctly aligned. Another incentivebased paper focusing on the impact of authority on the information structure of the organization is Stein (2002). Stein draws a distinction between hard and soft information. When information is hard (or verifiable), there is no downside to maintaining a hierarchical structure as opposed to delegating authority. In this model, it is the absence of authority that creates incentives for workers, because they are motivated to produce more positive information for the management en route to making a stronger case for a larger share of the capital budget. Although Aghion and Tirole (1997) and Stein (2002) focus on the impact of authority on the information structure, Dessein (2002) provides a purely informational rationale for delegation, taking the information structure (in which the agent is better informed than the principal) as given. The agent, if granted authority, will make decisions that make use of all the privately held information. A prediction that emerges is that centralization of authority is only optimal if the principal has the information relevant to the main decisions or is able to verify the information provided by lower levels of the hierarchy. The central trade-off in Dessein’s model is between a loss of control under delegation and a loss of information under communication. Thus, delegation of authority serves as an alternative to communication of information. The upshot of this discussion is that theoretical arguments can be made for and against the delegation of authority in a team context (or an individual worker context), and it is an
68

empirical question how these various forces impact financial performance, on average, across organizations.
DATA AND MEASURES The data are from the management questionnaire in the 1998–2004 panel of the British WERS, jointly sponsored by the Department of Trade and Industry, ACAS, the Economic and Social Research Council, and the Policy Studies Institute. Distributed through the UK Data Archive, the WERS data are a nationally representative stratified random sample covering British workplaces with at least 10 employees except for those in the following 1992 Standard Industrial Classification (SIC) divisions: agriculture, hunting, and forestry; fishing; mining and quarrying; private households with employed persons; and extraterritorial organizations. Some of the 3,192 workplaces targeted were found to be out of scope, and the final sample size of 2191 implies a net response rate of 80.4% (Cully, Woodland, O’Reilly, & Dix, 1999) after excluding the out-of-scope cases. Data were collected between October 1997 and June 1998 through face-to-face interviews, and the respondent manager was usually the most senior manager at the workplace with responsibility for employment relations.
Financial Performance The 1998 cross-section asks respondents to rate the current financial performance of the workplace relative to that of others in the same industry. Responses include ‘‘A lot better than average,’’ ‘‘Better than average,’’ ‘‘About average for industry,’’ ‘‘Below average,’’ ‘‘A lot below average,’’ and ‘‘No comparison possible.’’ The financial performance question asked in 2004 for the 1998–2004 panel is somewhat different, and therefore, the same variable is not observed in both years. Respondents in 2004 are asked whether financial performance in the industry as a whole has improved, stayed the same, or deteriorated since 1998. Then, for each of those three possible responses, the respondent is asked about the improvement (or deterioration) of the workplace in question relative to the change in the industry. This information is insufficient to create a 2004 financial performance variable defined in exactly the same way as the 1998 variable, and for that reason, an analysis that incorporates establishment-level individual effects is not possible. Instead, I define the following discrete
Teams, Autonomy, and the Financial Performance of Firms
69
dependent variable indicating whether the workplace’s 2004 financial performance position (relative to the industry average) has improved, stayed the same, or deteriorated since 1998: Financial Performance=1 if (financial performance for establishments in the same industry has improved since 1998 and, compared with that improvement, this workplace’s financial performance has improved at a slower rate, or remained static, or actually deteriorated) or (financial performance for establishments in the same industry has stayed the same since 1998 and, compared with that stability, this workplace’s financial performance has deteriorated) or (financial performance for establishments in the same industry has deteriorated since 1998 and, compared with that deterioration, this workplace’s financial performance has deteriorated at a faster rate). = 2 if (financial performance for establishments in the same industry has improved since 1998 and, compared with that improvement, this workplace’s financial performance has improved at a similar rate) or (financial performance for establishments in the same industry has stayed the same since 1998 and, compared with that stability, this workplace’s financial performance has remained stable like the rest of the industry) or (financial performance for establishments in the same industry has deteriorated since 1998 and, compared with that deterioration, this workplace’s financial performance has deteriorated at the same rate as the rest of the industry). = 3 if (financial performance for establishments in the same industry has improved since 1998 and, compared with that improvement, this workplace’s financial performance has improved at a faster rate) or (financial performance for establishments in the same industry has stayed the same since 1998 and, compared with that stability, this workplace’s financial performance has improved) or (financial performance for establishments in the same industry has deteriorated since 1998 and, compared with that deterioration, this workplace’s financial performance has remained stable or actually improved since 1998). Teams Starting with the 1998 cross-section, the WERS asked questions about the nature and use of teams. The same questions are asked in the 2004, both for the cross-section and for the 1998–2004 panel. The respondent manager is asked to report the proportion of employees in the largest occupational group at the workplace that works in formally designated teams. Responses are in the following discrete categories: ‘‘All 100%,’’ ‘‘Almost all 80–99%,’’
70
JED DEVARO
‘‘Most 60–79%,’’ ‘‘Around half 40–59%,’’ ‘‘Some 20–39%,’’ ‘‘Just a few 1–19%,’’ and ‘‘None 0%.’’ Following my earlier studies of teams, in both years, I aggregate this variable to a binary indicator of whether teams are used in the largest occupational group. I then define the following four dummies: Teams00 =1 if teams are not used in the largest occupational group in either 1998 or 2004 =0 otherwise Teams01 =1 if teams are used in the largest occupational group in 2004 but not in 1998 =0 otherwise Teams10 =1 if teams are used in the largest occupational group in 1998 but not in 2004 =0 otherwise Teams11 =1 if teams are used in the largest occupational group in 1998 and 2004 =0 otherwise There are two reasons for aggregating the original seven-valued teams measure to a binary variable. First, classification errors can be expected to be smaller for the binary measure (that simply captures whether teams are used, or not, in the largest occupational group) than for the original measure. This is particularly important given that the teams questions pertain to the establishment’s largest occupational group. For example, consider two establishments, A and B, each of the same size. In A, the establishment’s largest occupational group comprises two-thirds of the establishment’s workforce, whereas in B, it comprises less than 10%. If A responds that ‘‘Some (20%–39%)’’ of its largest occupational group is in teams, whereas B responds that ‘‘Around half (40%–59%) of its largest occupational group is in teams, a seven-valued teams variable would indicate that teams are more prevalent in B, whereas the reverse is true at the establishment level (and note that the dependent variable pertains to organizational performance at the establishment level). This type of classification problem is mitigated by considering a binary team measure. A second reason for aggregating the teams variable to two categories is parsimony. Standard errors are large in most specifications even using binary measures of teams and autonomy, and therefore, more general models are impractical.

71
Autonomy The measure of autonomy is given by the following WERS question: For establishments that report the use of formally designated teams in the largest occupational group, the respondent manager is asked to respond ‘‘Yes’’ or ‘‘No’’ to the following statement: ‘‘Team members jointly decide how the work is to be done.’’ This was also the primary autonomy measure I investigated in DeVaro (2006), and it corresponds closely to the notion of autonomy used in the interdisciplinary literature on self-managed teams. It is argued in the organizational behavior literature that team members are motivated when ‘‘the task provides group members with substantial autonomy for deciding about how they do the work [emphasis added] – in effect, the group ‘owns’ the task and is responsible for the work outcomes’’ (Hackman, 1987, p. 324). In the economics literature, notions of autonomy, at the level of both individual workers and teams, are similar, focusing on the right of workers to select actions (i.e., tasks) affecting part or the whole of an organization (Simon, 1951). From the autonomy and the teams questions, I construct the following binary indicators: Teams01a

Employer Characteristics Some of the empirical specifications of the next section include controls for employer characteristics, measured in 2004. These are as follows: the natural logarithm of establishment size (all workers currently on payroll at the establishment), a binary indicator for whether any of the employees at the establishment are unionized, an indicator for whether the establishment is a single-establishment firm, industry dummies (manufacturing; electricity, gas, and water; construction; wholesale and retail; hotels and restaurants; transport and communication; financial services; other business services; public administration; education; health; and other community services), and dummies for the establishment’s largest occupational group (managers and administrators, professional occupations, associate professional and technical occupations, clerical and secretarial occupations, craft and related occupations, personal and protective service occupations, sales occupations, plant and machine operatives, and other occupations).
EMPIRICAL TESTS The first part of the analysis aims to measure the effect of teams on financial performance, without regard to whether the teams are autonomous or nonautonomous. I estimate an ordered probit model in which Financial Performance is the dependent variable, and the key independent variables are Teams00, Teams01, and Teams10. I report the results of four specifications. The first includes only the aforementioned independent variables. The second includes those independent variables plus controls for firm characteristics. The third and fourth repeat the first and second, respectively, using a more restricted subsample that requires that each establishment’s largest occupational group be the same in 2004 as it was in 1998. This is potentially important. For example, suppose the observed teams (or autonomy) variable changes in 2004 from its value in 1998. This could be because of a true change or because the various occupations at the establishment changed in their relative sizes and that the new (i.e., 2004) largest occupational group is different from the old (i.e., 1998) one with respect to its use of teams or autonomy. In this case, it would misleadingly appear that the employer was instituting changes in teams or autonomy. The sample restriction eliminates this concern, at the expense of sacrificing over 30% of the observations in models where precision is already low for some of the key parameters. For this reason, I present both sets of results. Descriptive statistics are presented in Table 1, and results for the four specifications are displayed in Table 2.

teams on financial performance, given the previous literature, is positive. Although most of the prior empirical literature finding support for this positive predicted effect focuses on intermediate measures of organizational performance (e.g., labor productivity), in my earlier study using the 1998

WERS cross-section (DeVaro, 2006), I found a positive effect on financial performance. This directional hypothesis suggests one-tailed significance tests, which I use throughout the analysis. Across each of the four specifications, only the coefficient of Teams10, which is negative, is significant at the 10% level. The result suggests that, relative to establishments that used teams in the largest occupational group both in 1998 and in 2004, those that started with teams in 1998 and then abandoned them between 1998 and 2004 had a lower probability of experiencing improvements in financial performance relative to the industry average during 1998–2004. The result is consistent with the hypothesized positive effect of team production on financial performance. Note that the magnitude of the Teams10 coefficient is largely unchanged across specifications. This insensitivity of the coefficient to the specification might be used as the basis for focusing on the models that exploit the larger sample size without the sample restriction (i.e., specifications 1 and 2, as opposed to 3 and 4). To be conservative, however, my preference is to focus on specification 4 when drawing inferences from Table 2 and from subsequent analyses. I also investigate whether the effect of teams on financial performance is affected by the starting level (i.e., the 1998 level) of financial performance. I do this by first constructing two binary variables; the first equals 1 if 1998 financial performance was above the industry average (and 0 otherwise), and the second equals 1 if 1998 financial performance was ‘‘a lot above’’ the industry average (and 0 otherwise). I interact these two dummies with each of Teams00, Teams01, and Teams10, producing six two-way interactions that I add to each of the four empirical specifications discussed in Table 2. Results are displayed in Table 3. Three results emerge from the table. First, focusing on specification 4, the earlier result from Table 2 regarding Teams10 appears to vanish for establishments whose 1998 financial performance was above the industry average, so that the lower probabilities of improved financial performance between 1998 and 2004 that are experienced by establishments that start out with teams and subsequently abandon them apply only to those establishments that started the period with financial performance at or below the industry average. Although this result qualifies and refines the earlier result from Table 2, in that it does not apply to establishments whose 1998 financial performance was above the industry average, it is still consistent with the expectation from the prior literature of a positive effect of teams. Second, in contrast to the earlier result from Table 2, the coefficient of Teams01 in specification 4 is positive and statistically significant, suggesting that employers that did not use teams in the largest occupational group in

1998 but added them prior to 2004 experienced, on average, a higher probability of improved financial performance relative to employers that used teams consistently in both years. However, this result appears to be absent for those establishment that started the period with financial performance above (or a lot above) the industry average, pertaining only to those establishments starting the period with financial performance at or below the industry average. Overall, the result is consistent with a positive effect of teams, given that (if teams are indeed beneficial) adding teams where they are absent can be expected to improve financial performance more than continuing to use them where they are already present. Third, in contrast to the earlier result from Table 2, the coefficient of Teams00 in specification 4 of Table 3 is positive and statistically significant, suggesting that employers that used teams neither in 1998 nor in 2004 in their establishment’s largest occupational group experienced, on average, a higher probability of improved financial performance relative to employers that used teams consistently in both years. This result appears counter to the hypothesis of a positive effect of teams on financial performance. However, it should be noted that the result is clearly absent (and may even be reversed) for establishments that started the period with financial performance a lot above the industry average. Furthermore, while I focus throughout on specification 4 given that I see it as most conservative, it should be noted that the coefficient of Teams00 is statistically insignificant in the other three specifications. Taken as a whole, the results from Table 3 seem consistent with a positive effect of teams on financial performance, although there is less consistency across specifications of Table 3 than there was for Table 2. The second part of the analysis aims to distinguish between the effect of selfmanaged (or autonomous) teams and closely managed teams on financial performance. I start by estimating noninteractive specifications that parallel those in Table 2, with the difference being that instead of including the three independent variables Teams00, Teams01, and Teams10, I use the larger set of indicators (distinguishing teams by whether or not they are granted autonomy) described in the previous section. The previous literature generally predicts that the benefits of teams to organizational performance tend to be most pronounced when the teams are autonomous. An exception can be found in my earlier work (DeVaro, 2006) where there was a positive relationship between teams and financial performance but no incremental positive effect of autonomy; this result was contrary to the conventional wisdom. However, it must be emphasized that most of the empirical teams literature has not used financial performance as a dependent variable, but rather some intermediate measure such as labor productivity.

Results from the noninteractive specifications are displayed in Table 4. Again, in drawing inferences, I focus on specification 4. The first result echoes the earlier result from Table 2, namely that establishments that start the period with teams and subsequently abandon them experience a lower probability of improved financial performance over the period than those that continue using teams. However, this result appears to be true only for autonomous teams. There is no evidence of a negative effect from abandoning teams if the teams were initially nonautonomous. This result is

consistent with the bulk of the literature arguing for the merits of autonomous teams. The second result is that employers that use nonautonomous teams in both years have a lower probability of improved financial performance over the period than those using autonomous teams both periods. This result also favors granting teams autonomy, given that teams are used. However, the results also suggest that employers that use nonautonomous teams in 1998 and then switch to autonomous teams during 1998–2004 experience a lower probability of improved financial performance, relative to the reference group. This result is more favorable to nonautonomous or closely managed teams. I also investigated whether the preceding effects depend on the level of financial performance at the start of the period. To keep the number of twoway interactions manageable, I created only one dummy (as opposed to two in the analyses of Table 3) indicating whether current financial performance in 1998 is above average for the industry or a lot above average for the industry (=1) versus at or below the industry average (=0). I interacted this dummy with the independent variables of interest from Table 4, reestimating all four specifications including all the interactions. Results are displayed in Table 5. The first result from the table is that employers that use no teams in 1998 and subsequently introduce nonautonomous teams during 1998–2004 experience a higher probability of improved financial performance during the period than employers who use autonomous teams in both years. However, this result only holds for employers with financial performance at or below the industry average in 1998 and is reversed for higher-performing employers. It is interesting to note that the corresponding result does not hold when autonomous teams are introduced (given that no teams were used in 1998); in that case, there is no evidence of a difference relative to the reference group. The second result, which parallels a result from Table 4, is that employers that start with autonomous teams and subsequently abandon them in favor of no teams are less likely than the reference group to experience improved financial performance during the period. However, this effect is mitigated for establishments with higher-than-average (relative to the industry) financial performance in 1998. The third result, also paralleling a result from Table 4, is that employers using nonautonomous teams in both years have a lower probability of improved financial performance during the period than the reference group. The fourth result, also paralleling a result from Table 4, is that employers that start off with nonautonomous teams and then grant teams autonomy

during the period experience a lower probability of improved financial performance during the period, relative to the employers in the reference group. However, this is true only for establishments with financial performance that is at or below the industry average in 1998. For such employers, the result is more favorable to nonautonomous or closely managed teams than to autonomous or self-managed ones.
DISCUSSION AND CONCLUSION The results of the previous section are of interest because, in contrast to my earlier work on the same subject using only cross-sectional data, the present results exploit variation not just across production units but also over time. Aiding comparability to my earlier results is the fact that the setting is the same (a random sample of British establishments, first sampled in the year of my original studies) and that most of the key measures are the same. In particular, I focus on financial performance, which is a rare outcome variable in an empirical literature that focuses more heavily on intermediate measures of organizational performance. Another positive feature of the present panel is that while it consists of only two years, they are six years apart. Although temporal variation in HR practices is always desirable in addition to crosssectional variation, there is usually little within-establishment variation in practices from one year to the next. But six years is a long enough span to generate a decent amount of temporal variation in the practices of interest. Despite these advantages, the results of the previous section must be qualified on several grounds. First and foremost, most of the results are estimated with low precision. In part, this is a consequence of the much
82
JED DEVARO
smaller sample sizes associated with the 1998–2004 WERS as opposed to the WERS cross-sections. Another factor likely contributing to low precision is the fact that the key questions about practices pertain not the establishment as a whole but rather to the establishment’s largest occupational group, whereas the dependent variable is measured at the establishment level. Yet another factor potentially contributing to low precision is the dependent variable itself; while it is interesting to examine as broad an outcome variable as financial performance, it might be expected that effects of teams (and autonomy) might be harder to detect in this case than for an intermediate measure of performance (e.g., labor productivity) that is more directly impacted by HR practices and subject to a smaller set of stochastic influences. Second, although temporal variation in the practices of interests could be exploited in the 1998–2004 panel, I was unable to incorporate establishment-level individual effects into any of the statistical models. The reason for this is that the dependent variable measuring financial performance that was measured in 1998 was not measured in the same way in 2004. Third, to be conservative, I have focused on the most controlled specifications that restrict the sample to those establishments for which the largest occupational group is the same in both 1998 and 2004. But it should be noted that the results sometimes differ across the other specifications, which is another consequence of low precision. Although I have focused on the fourth specification in assessing the overall pattern of results, other readers of the same results may have a different interpretation that assigns different relative weights to the four specifications. Low precision of the estimates notwithstanding, some patterns in the data emerge that are worth noting in light of the previous literature. In particular, the results seem consistent with a positive effect of teams on financial performance, which is consistent with the findings from my cross-sectional work on this question in DeVaro (2006). The second result, also consistent with my earlier cross-sectional work in DeVaro (2006), is that results are mixed concerning whether autonomous or nonautonomous teams are better in terms of financial performance. Some results are more favorable to autonomous teams and some to nonautonomous teams. These results suggest that granting teams autonomy is less essential than commonly argued in the literature in terms of benefits to financial performance, although it must again be noted that financial performance rarely appears in this literature as an outcome measure. The 1998–2004 WERS panel offers a rare opportunity to analyze these questions in a panel setting; usually such panels involve much narrower samples involving one or a small number of firms. Unfortunately, low
Teams, Autonomy, and the Financial Performance of Firms
83
precision is a significant impediment to extracting robust insights from this sample. Looking to the future, it is hoped that future waves of WERS and similar data sets build on the strengths of the 1998–2004 panel while repairing some of the weak points. In particular, it would be helpful for outcome variables such as financial performance to be measured in the same way in each year so that individual effects can be incorporated into statistical models. It would also be helpful to step away from the focus on the establishment’s ‘‘largest occupational group,’’ given that this creates some incompatibility between the outcome measure (which is at the establishment level) and the key independent variables; this would also eliminate the problems that arise when the largest occupational group changes across years in the panel. Finally, it would be helpful to maintain the usual sample sizes but restricting the sampling frame to a particular industry. This would have the advantage of increasing precision and sharpening results by cutting down on the significant heterogeneity that exists across production units in a nationally representative random sample, while at the same time avoiding the negatives of the other extreme, which is convenience samples of one or a small number of firms that may yield highly idiosyncratic results. My hope is that this chapter will stimulate collection of such samples in the future.

HOW DO RULES AND COSTS AFFECT A FIRM’S SETTING OF BENEFITS? THE CASE OF HEALTH INSURANCE AND WORKFORCE SKILLS Nan L. Maxwell ABSTRACT Institutional rules and economies of scale can create incentives for firms to make inframarginal decisions when offering fringe benefits. We examine how such incentives might affect a firm’s offer of health insurance. We develop and estimate an empirical model of the firm’s offer of health insurance that includes incentives created by rules and economies of scale. We quantify the behavioral manifestations from rules and costs as recruiting difficulty in areas outside those in which compensation is set and the percentage of high-skilled jobs in the firm and use the California Health and Employment Surveys (CHES) to estimate the model. We show a 10–13 percentage point increase in the probability of a firm offering workers health insurance in jobs outside of those in which compensation is being set, if the recruiting difficulty lies in mid- or highskilled positions. This increase is about twice the size of the increase

associated with recruiting difficulty in the position in which compensation is negotiated. A failure to control for the influence of inframarginal decision making when estimating the wage-insurance tradeoff helps produce wrong-signed estimates. By bringing institutional rules and economies of scale into the framework of a firm’s offer of fringe benefits, we help move the focus of the fringe benefit-wage tradeoff away from the individual level. Keywords: Fringe benefits; employer–sponsored health insurance; wage-benefit tradeoff; workforce skills JEL classification: M52 When a worker shops for a job, two questions often are paramount: what wages will I receive and what benefits will I be offered? Some workers, such as youth and those with a relatively low income may focus heavily on wages when weighing a job offer, whereas others such as heads of families and those with a relatively high income, may actively scrutinize the benefit package offered. Because wages represented only 70.8 percent of worker compensation in 2009 (EBRI, 2010), heterogeneous workers have the ability to sort among firms whose compensation package best matches their preferences and firms have the incentive to tailor their compensation package to attract workers with desired characteristics (Hirth, Baughman, Chernew, & Shelton, 2006; Monheit &Vistnes, 1999). Rosen’s (1986) analysis of compensating differentials grounded research on the firm’s decision to offer benefits to workers as a tradeoff with wages. Profit maximizing firms must trade monetary and nonmonetary benefits in compensating workers to keep costs competitive and utility maximizing workers will trade benefits for wages. Individual-level negotiations of compensation might lead to wide variations in the composition of a firm’s compensation package to homogeneous workers as long as firms remain unconstrained, transaction costs are zero, worker preferences for the form of compensation vary, and workers sort among firms based on benefits. However, because rules constrain a firm with respect to individual-level negotiation of compensation and create economies of scale when a firm offers a particular benefit, the firm’s decision to offer a benefit becomes inframarginal, with a low marginal cost of extending the offer to a large pool of workers once the decision to offer is made.

This research assesses the behavioral manifestations of inframarginal decision making in the firm’s offer of health insurance, one of the most critical components of a fringe benefit package when workers sort among firms (Lehrer & Pereira, 2007). We argue that recruiting difficulties in positions other than the one in which compensation is set and the proportion of highskilled workers in the firm quantify manifestations of the ways in which rules and costs influence a firm’s decision to offer health insurance. We support their influence using the California Health and Employment Surveys (CHES), a database of 1,427 firms and 2,673 jobs in 27 Northern California and show how their omission in estimations of the wage-insurance tradeoff produces downward biases in the estimated wage-health insurance tradeoff.
FRAMEWORK A firm’s offer of health insurance is heavily regulated. Some legislation and rules are designed to incentivize a firm to offer insurance by lowering its cost. Under current law, employers may deduct the expenses they incur for employees’ health insurance and health care as a business expense (as they do for wages) but are exempt from paying the 6.2 percent payroll tax for Social Security (for workers below its maximum wage) and the 1.45 percent payroll tax for Medicare. These exemptions present the firm with a tax savings over wage compensation if it offers health insurance in lieu of wages. Still other rules are designed to ensure equity in coverage, with these rules generally raising the cost to the firm of offering health insurance. Many state mandates and some provisions of the newly legislated Affordable Care Act (ACA) require coverage of specific treatments or conditions. Section 105(h) of the Internal Revenue code prohibits discrimination in the offering of health insurance for firms with self-insured health plans1 (EBRI, 2009a) and cafeteria plans2 that include health insurance (nondiscrimination rule). The general idea behind the nondiscrimination rule is that benefits to higher-paid employees must be equivalent to those offered to lower-paid employees. For a plan to be nondiscriminatory it must pass one of the three coverage tests: 70 percent of all employees benefit under the plan; the plan benefits 80 percent of eligible employees and 70 percent of all employees are eligible; and the plan benefits a nondiscriminatory classification of employees (e.g., the same type and level of benefits are available to all). Firms offering multiple medical plans are unlikely to pass either the first or second test because employees are likely to be dispersed among the various options, hence most firms satisfy the nondiscrimination rule by offering the same
92
NAN L. MAXWELL
plan to all eligible workers. This nondiscrimination rule affects a relatively large percentage of workers, albeit those employed in large firms. In 2008, 89 percent of workers employed in firms with 5,000 or more employees were in self-insured plans, leaving 55 percent of workers with health insurance coverage through a self-insured plan (EBRI, 2009b).3 When firms offer health insurance through a third-party, they are not affected by the nondiscrimination rule, however, many of the same restrictions arise from the contractional conditions the insurer requires to provide insurance. Because third-party insurers actively work to reduce the probability of adverse selection in the pool of individuals they cover (i.e., attracting a disproportionate share of people in poor health into their pool), they frequently impose many of the same minimum coverage restrictions contained in the nondiscrimination rule. Their interest lies in creating a group of workers that is not formed for health-related purposes because such a group is more likely to approximate a random sampling of the population, be actuarially sound, carry a lower probability of adverse selection, and have predictable expected costs of health care that are relatively stable over time. Insurers frequently structure their contracts to reward large, nonselect groups with explicit conditions on eligibility for coverage and lower premium prices for larger groups.4 The consequence of these rules is that the startup cost of offering insurance for a firm is high because it must meet conditions set by the nondiscrimination rule and third-party insurers. Economies of scale arise because larger groups face lower per-worker administrative costs for insurance (i.e., marginal cost is declining). Thirdparty insurers benefit from contracting with a single, large firm in communicating with only a single individual or department, claims processing, benefits administration, and medical underwriting. Insurance brokers commissions therefore consume 9 percent of the premium dollar for small firms but less than 0.1 percent for large firms (Yegian, 1999). Economies of scale also arise from declining administrative costs within the firm from less expensive and more competent governance structures in larger firms (Williamson, 1975) and the gains from specialization in purchasing and administering health benefits. These externally and internally developed economies of scale in offering health insurance decrease its cost as firm size increases. As a result, administrative costs consume nearly 40 percent of every premium dollar for firms with 1–4 employees and about 5.5 percent for employers with 10,000 or more employees (as cited in Yegian, 1999). Administrative cost structures are also impacted with the number of plans offered (Moran, Chernew, & Hirth, 2001). As a firm increases the number of plans offered it must communicate the details of different plans to workers,

93
negotiate with different insurers, and face higher load charges and potentially higher premiums as the pool of workers in any one plan is reduced. In short, forces within the firm align with incentives provided by thirdparty insurers to create relatively high fixed costs to offering insurance and relatively low marginal costs of expanding the pool of workers covered. The large fixed costs of initially offering insurance suggest that profit maximizing firms will offer health insurance only if the perceived benefits are high. One potentially high set of benefits is attracting workers with needed skills. Because workers sort across firms based on their preferences for health insurance (Goldstein & Pauly, 1976), firms can structure the health insurance offer to meet the preferences of workers with needed skills. This strategy works if preferences for wage and nonwage compensation vary by skills, a premise supported by research showing a correlation between wages, which are associated with skills, and preferences for nonwage compensation. Low-wage workers often prefer wages to nontaxed health benefits (Currie & Yelowitz, 2000) as they often have a Medicaid safety net and low marginal tax rates. In contrast, high-wage workers often prefer nontaxed health benefits to wages, at the margin, as they face high marginal tax rates.5 If a firm has a workforce with mixed preferences, research suggests it bases its offer on the preferences and prices faced by its median workers (Goldstein & Pauly, 1976). Highly compensated workers have a heavy influence on the offer (Gruber & Lettau, 2004), perhaps because firms want to attract skills and realize their loss by not offering insurance to highwage workers. Using health benefits as a means to attract workers with needed skills might be especially appealing when firms face bottlenecks in hiring. Just as a firm might increase wages to attract workers with needed skills, it might also decide to offer health insurance to increase compensation, especially if the hiring difficulty lies in recruiting high-skilled workers, who have a strong preference for nonwage compensation. Although both worker preferences and recruiting difficulties in areas of labor bottlenecks might entice a firm to bear the relatively high fixed cost and offer health insurance, its low marginal cost of extending the offer to a large pool of workers suggests the firm might extend the offer to workers throughout the firm once it decides to offer it. This inframarginal decision making means that workers who might not value an offer of health insurance highly will have an increased probability of receiving an offer simply because a high proportion of workers that value it highly are employed in the firm. Supporting this argument is research showing a pronounced incongruence between the offer of health insurance and worker preferences for high-wage workers in low-pay firms and low-pay workers in
94
NAN L. MAXWELL
high-pay firms (Carrington, McCue, & Pierce, 2002). Workers that receive an offer of health insurance but do not value it highly might not be willing to trade it for wages, however, and firms, who face a relatively low cost of offering it, might not reduce wages for fear of not being able to attract workers. Under such circumstances, the negative tradeoff between wages and health insurance would not be shown in empirical estimations. This research examines how the behavioral manifestations of the high fixed and low marginal costs that a firm faces in offering health insurance – recruiting difficulties and workers preferences – might alter a firm’s probability of offering health insurance and produce a downward bias in the estimated work-insurance tradeoff. Specifically, we argue that the inframarginal decision to offer health insurance leads to two empirically testable propositions. First, recruiting difficulties anywhere in the firm, particularly among high-skilled workers, and an increasing percentage of high-skilled workers will increase the probability that a firm offers health insurance. The focus on high-skilled workers arises from their greater desire to trade wages for insurance and more critical role in production than workers with lesser skills (e.g., the lack of availability of production substitutes decreases as skill levels increase). As a result, rules and costs will incentivize firms to offer insurance in positions other than the one with recruiting difficulty and firms with a high proportion of high-skilled workers will be more likely to bear the cost of offering insurance with a low marginal cost extending it to additional workers who may not value it highly. Second, the estimated tradeoff between wages and health insurance will become stronger (or less positive) with controls for the inframarginal factors that increase the probability of a firm offering health insurance. Although compensating differentials predicts that firms will trade wages and health insurance in compensating workers, both rules and the low marginal cost of offering insurance may negate this tradeoff at the margin for it costs the firm little to extend the offer once the decision to offer it has been made. The tradeoff for the firm, at the margin, may therefore be close to zero for many workers, which would be verified as controls for the initial offer decision are included in empirical estimations.
RESEARCH DESIGN Estimations of whether a firm’s offer of health insurance, particularly those estimating a tradeoff with wages, are often confounded by unobserved

95
(to the researcher) individual, firm, and job heterogeneity that influence both the offer of health insurance and wages. One approach in controlling such heterogeneity is through the design of the research. Researchers have controlled for unobserved heterogeneity with experimental designs,6 differencing with multiple individual-level observations over time (e.g., Smith & Ehrenberg, 1983), and modeling individual variation in demand for health insurance through intrafamily trades (Olson, 2002). Of note, studies have been grounded in individual not firm-level estimations. This research takes a slightly different approach and uses firm and joblevel data collected from establishments7 to control for unobserved heterogeneity. Firm-level data capture the offer of health insurance at the appropriate decision-making level instead of relying on individual-level data to approximate the firm’s decision, as does the vast majority of empirical studies of the wage-health insurance tradeoff.8 We minimize firm-level heterogeneity using separate estimations on different samples of jobs drawn from the same sample of firms, which stands in contrast to using three different samples of firms for three skills groups. This more typical approach produces a fair amount of firm-specific unobserved heterogeneity. Heterogeneity in skill requirements is minimized by examining starting wages in jobs at each of the three narrowly defined skill position levels in the firm:9 ‘‘low-skilled’’ (requiring a new worker to have no more than a high school education and no more than a year of work experience), ‘‘midskilled’’ (requiring some college or one to three years of work experience), and ‘‘high-skilled’’ (requiring at least a college degree and/or extensive work experience). Unobserved heterogeneity in the wage-insurance tradeoff is further reduced by using starting wages within each relatively narrow category of positions. Starting wages contain less heterogeneity than current wages because they occur at the start of the employment relationship when employers are largely ignorant of the productivity of new hires. This ignorance makes starting wages based less on observed productivity, training, and learning-by-doing than current wages and makes the variance in worker productivity in the employer’s eyes relatively small. As a result, much of the unobserved worker heterogeneity that determines wages and plagues econometric estimation of wage-insurance regressions is mitigated when using starting wages. Despite these design advantages, skill-based unobserved heterogeneity in estimations might exist in our three samples of jobs, particularly as increased education and work experience requirements help differentiate worker productivity (i.e., in mid and high-skilled jobs).

DATA AND EMPIRICAL ANALYSIS We used the California Health and Employment Surveys (CHES) to test our propositions. CHES is a cross section of 1,427 firms in 27 Northern California counties. Randomly selected firms were called from July 2005 through September 2006 with a 67-percent response (Maxwell, 2007). Firms with at least 51 employees were oversampled, with weights developed that could be used to ensure that analysis reflects the distribution of firms in the United States with respect to size and industry. The targeted respondent for answering the survey was ‘‘the person with knowledge about benefits and jobs.’’ Government agencies and firms with fewer than five workers were excluded from the sampling frame. Firm-level data in the CHES include whether it offers health insurance, the percentage of workers employed in jobs at each skill level, and firm characteristics including industry, location, nonprofit status, and number of employees.10 Job-level data include information on the typical job at each skill level, including the firm’s difficulty in recruiting workers with needed skills,11 average starting wage and whether the incumbent worker is represented by collective bargaining. These data allow us to extend a tradition model (e.g., Claxton, DiJulio, Finder, & Becker, 2007; Glied & Zivin, 2004; Leibowitz & Chernew, 1992) of whether a firm (f) offers health insurance (H) as a function its characteristics (C: size, presence of a union, for profit, rural location, and industry) to include a vector of variables that capture difficulty in recruiting workers (R) with needed skills in the typical job at each skill level (s) and a measure of the percentage of workers in high-skilled jobs in (HS):12 H f ¼ a0 þ Rs ar þ a1 HSf þ Cf ac þ 1
(1)
where e is a disturbance term. Of note, C in this estimation includes size and union variables that might be considered measures of institutions or costs. We classify them as firm characteristics in our equations because they are included in traditional models estimating the firm’s offer and we wish to focus our study on extensions to this model (i.e., R and HS). Estimation of Eq. (1) without the extensions (i.e., ar ¼ a1 ¼ 0) provides a benchmark of the estimated coefficient size on firm characteristics (ac) on the probability of offering health insurance in traditional models. These benchmark coefficients can be compared to those obtained when our measures of recruiting difficulty and workforce skills are included to determine biases with their exclusion. Our first proposition posits that recruiting difficulties and an increasing percentage of high-skilled workers in the firm will increase the probability

97
that a firm offers health insurance, which we initially support with positive and significant (pr.05) coefficients on the measures of recruiting difficulty (ar) and high-skilled workers (a1) in Eq. (1) estimations. A more robust test will use job-level data to estimate the same general model outlined in Eq. (1) for jobs at each skill level. In this analysis we examine whether recruiting difficulties reflect market-based forces (i.e., increased compensation to attract workers with needed skills) or rules and cost structures that incentivize a firm to offer insurance to workers in jobs not necessarily affected by recruiting difficulties. We estimate the offer of health insurance to workers at each skill position level as a function of recruiting difficulties in the job at that skill level in which compensation is negotiated (su), which reflects market forces, and recruiting difficulties in jobs at other skill position levels (Rs–Rsu or Rus), which reflects rules and economies of scale that increase the probability of offering health insurance to workers in jobs outside the one in which the firm has difficulty in recruiting. We estimate: H f ;s ¼ a20 þ a21 HSf þ R0s a2r þ a22 Rs0 þ Cf a2c þ 2
(2)
using the same general interpretations and step approach in estimations described earlier. The second proposition posits that the estimated tradeoff between wages and health insurance will become stronger as controls for recruiting difficulty and high-skilled workers are included in the estimation. To test this proposition, we include the average starting wage13 (Ws) into Eq. (2) such that: H f ;s þ b0 þ b1 HSf þ R0s0 br þ b2 Rs0 þ Cf bc þ bw W s þ 3
(3)
Should bw become more negative (less positive) as Rus and HS are include into the model, our second proposition would be supported. We use ordinary least squares to estimate all models, which allows us to quantify the percentage increase in the probability of the firm making an offer of health insurance that is associated with a change in the independent variable.14 We use the unobserved heterogeneity in skill requirements that is increasingly present in higher-skilled jobs to perform a sensitivity analysis of our results. Because low-skilled jobs are relatively homogeneous with respect to skill requirements (i.e., require no more than a high school education and no more than one year of work experience), we expect skill differences that increase both wages and health insurance to be relatively minimal. Remaining heterogeneity would reside in firms and job attributes
98

(e.g., risk and capital usage) that determine productivity or compensation. However, as skill requirements increase (i.e., education or work experience), we expect heterogeneity to increase with variability in the nature of the skills acquired (i.e., as the sample moves from low- to high-skilled jobs), which will reduce estimated parameters in our models (a’s and b’s). We therefore expect propositions to have the strongest support when estimated on the sample of low-skilled jobs. The CHES data are uniquely suited for our study not only because they contain measures that capture recruiting difficulties and percent of highskilled jobs but also because they contain a sample of relatively typical firms and jobs. Of primary importance, firms in the CHES database show characteristics that likely subject them to the rules and economies of scale discussed earlier. Just over 5 percent are self-insured and just over 21 percent offer a cafeteria plan, with about 82 percent including health insurance in it (Table 1). These firms were subject to the nondiscrimination rule when data were collected. About 65 percent of firms have fewer than 20 workers and about 21 percent have 20–50 workers, which generally exposes them to experience rating and relatively high administrative costs in offering health insurance.

with the skill requirements of the job (i.e., increase as the sample of jobs moves from low-skilled to high-skilled). About 76 percent of firms housing the sample of low-skilled jobs offer health insurance compared to about 83 percent of firms housing the sample of high-skilled jobs. Wages increase from an average of $11.57 in low-skilled jobs to $29.98 in high-skilled jobs and difficulty in attracting workers with needed skills increases from about 33 percent in low-skilled jobs to 59 percent in high-skilled jobs. The percentage of high-skilled workers in the firm increases from about 27 percent in the sample of low-skilled jobs to about 45 percent in the sample of high-skilled jobs (Table 2). CHES data provide evidence that heterogeneity increases as skill position levels increase. Both the coefficient of variation for wages and the coefficient of determination (R2) of the traditionally specified Eq. (2) estimation (ar ¼ a1 ¼ a2 ¼ 0) of health insurance at each skill position level can be used to assess unobserved heterogeneity in each of our samples of jobs. The CHES data show the lowest coefficient of variation for wages and highest R2 in low-skilled jobs, as would be the case if unobserved heterogeneity in skills requirements increased with the skill requirements of the job (Fig. 1).

relationships between firms that offer and do not offer health insurance, we examine the coefficient of variation for wages separately for each type of firm (Fig. 2). Firms that offer health insurance have a lower coefficient of variation at each skill level than firms that do not offer it, as might be expected since compensation is more easily negotiated at the individual level without health insurance and a lower level of unionization. In firms that offer health insurance, the coefficient of variation rises with skill level, as expected. In firms not offering health insurance, the coefficient is highest in mid-skilled jobs and slightly higher in high-skilled than low-skilled jobs, which suggests a skill compression among workers in high-skilled jobs in firms that do not offer health insurance.
RESULTS As evidence that firms behave in accordance with the incentives provided by rules and economies of scale, CHES data show that about half the firms offer workers one health insurance plan only (Table 1). The percentage varies dramatically with firm size, as our framework suggests, with about 72 percent
102
NAN L. MAXWELL
of firms with fewer than 20 workers and 1 percent of firms with 1,000 or more workers offering only one plan. CHES data also suggest that 78 percent of firms offer the same benefits to all workers. Most firms (about 51 percent) cited hours or tenure work requirements as the way in which benefits differed (data not shown). No firm that differed in the benefits offered explicitly mentioned differences in health plans as the demarcation of different benefits, although about 15 percent mentioned that they varied benefits with union representation and about 19 percent mentioned differences along the lines of position level. Only about 10 percent of these firms explicitly mentioned that health benefits differed across job classifications, suggesting that only about 7.8 percent of firms differentiate their health insurance offer in ways that are inconsistent with the discussion in our framework. Our multivariate estimations using CHES data also provide support for both of our propositions about rules and costs. Firm-level estimations of Eq. (2) show that recruiting difficulty in any skill position level and the percentage of high-skilled workers in the firm increases the probability the firm will offer health insurance (Table 3), as predicted by our first proposition. The coefficients on recruiting difficulty are sizable and increase with the skills needed in the job. If a firm has difficulty recruiting appropriately skilled workers in high-skilled positions, it has about a 13 percentage point increased probability of offering health insurance, while a firm with recruiting difficulties in low-skilled positions has only a 5.7 percentage point increase (Table 3, column 2). Although the coefficient on the percentage of high-skilled workers seems relatively small (0.002), a 20 percentage point increase in the percent of high-skilled jobs in the firm – roughly the difference between our samples of low- and high-skilled jobs – produces a 4 percentage point increase in the probability of a firm offering health insurance. Of note, this influence is significant only for workers in low- and mid-skilled positions.15 Our more robust test of the first proposition uses job-level data to examine the two distinct components of the recruiting difficulty measures: Rsu, which measures the market-force influence of increasing compensation with recruiting difficulty in the job, and Rus, which measures the influence of rules and economies of scale on health insurance with recruiting difficulty in jobs in which compensation is not being set. Results of these estimations suggest that market forces (along the diagonal in Table 3) increase the probability of offering health insurance by about five to six percentage points, irrespective of the skill position level. Recruiting difficulty in positions other than the one in which compensation is negotiated (rules and costs) has a stronger influence if the difficulty lies in recruiting workers in

mid- or high-skilled positions. Firms having difficulty recruiting appropriately skilled workers in mid- or high-skilled jobs have a 10 and 13 percentage point increase in the probability of offering health insurance.16 If, however, a firm has difficulty recruiting in low-skilled jobs, the probability of workers in mid- and high-skilled jobs receiving an offer of health insurance is not significantly increased. Estimations also support our second proposition that the estimated tradeoff between wages and health insurance becomes stronger with controls for recruiting difficulties and workforce composition. We tested this proposition by estimating two versions of Eq. (3): the traditional tradeoff model in which the measures of recruiting difficulties and percent of high-skilled

workers are not included, and a model that includes these measures. The traditional estimation on the sample of low-skilled jobs (Table 4) shows a positive and significant (pr0.05) wage coefficient consistent with much of the empirical research on the wage-insurance tradeoff. As we add the variable that captures the recruiting difficulty in the job (Market Forces column), the wage coefficient becomes insignificant but remains positive. As we add variables that capture the recruiting difficulty in other skill position levels, the wage coefficient becomes negative but insignificant. These results support the proposition that a failure to control for a firm’s behavioral manifestations of accompanying rules and economies of scale might contribute to the failure of empirical research to support a tradeoff between wages and health insurance. These results break down somewhat as Table 4.

we increase the heterogeneity in skill requirements of the job and estimate equations on the samples of mid- and high-skilled jobs (Table 5). For these samples, the wage coefficient is insignificant in all estimations, although it moves from positive to negative in the sample of mid-skilled jobs when measures of recruiting difficulty in high- and low-skilled jobs and the percentage of high-skilled workers are included. It remains positive and insignificant in the sample of high-skilled jobs in all model specifications.

Our sensitivity analysis suggests that the coefficient estimates on firm characteristics (ac) are fairly robust with respect to the level of unobserved job heterogeneity in skills while estimates of recruiting difficulties (ar) are sensitive to it. We tested for this robustness by estimation Eqs. (1) and (2) in stages: a traditional tradeoff model of the offer of health insurance in which the measures of recruiting difficulties and percent of high-skilled workers are not included and a model that includes both measures (Table 3). When the recruiting difficulty and percentage of high-skilled workers were included in the estimation, few differences arise in the size or significance of the coefficients on the firm characteristic variables (C), suggesting that models estimated without their inclusion might not produce biased estimates of the relationship between the firm’s characteristics and its decision to offer health insurance. Estimates of the relationship between our measures of behavioral manifestations of rules and economies of scale – recruiting difficulty in particular – appear to be influenced by the level of unobserved job-related heterogeneity, however (Table 3). The estimated coefficients from the sample of low-skilled jobs – our most homogeneous sample with respect to skill heterogeneity – are about the same size as for the sample of firms. However, results change when estimations are performed on the sample of mid- and high-skilled jobs. Recruiting difficulties in low-skilled jobs do not significantly increase the probability that a firm will offer health insurance in either sample and the influence of high-skilled workers is not significantly related to the probability of it offering health insurance in the sample of high-skilled jobs.
SUMMARY AND DISCUSSION We argued that the rules and economies of scale that firms face when offering fringe benefits create high fixed but low marginal costs in offering it and, as a result, move the wage-benefit tradeoff for the firm away from the individual level. We find empirical support for the argument using the case of health insurance. The nondiscrimination rule for firms that are self-insured or offer a cafeteria plan that includes health insurance, the conditions third-party insurers put on the coverage, and administration costs all create economies of scale in a firm’s offering health insurance and, as a consequence, create incentives for the firm to make inframarginal decisions as to whether it offers workers fringe benefits. One potentially large advantage that firms gain from bearing the high fixed cost of offering insurance is attracting workers with needed skills. Because workers sort across firms based on their preferences for health insurance, firms can use their offer of health insurance to attract

107
workers with desired skills. Once the firm’s decision to offer health insurance is made, the low marginal cost and institutional rules provide incentives to extend the offer to a large pool of workers. We argue that firms are likely to benefit from (and hence bear the high fixed cost of) offering health insurance as the percentage of high-skilled jobs increases because high-skilled workers have a stronger preference for nonwage compensation than low-skilled workers. We also argue that the low marginal cost of extending the offer to additional workers suggests that workers in low- and mid-skilled positions will have an increased probability of receiving an offer of health insurance with an increasing presence of highskilled workers in the firm. We also argue that difficulty in recruiting workers provides another incentive for firms to bear the high fixed cost of offering health insurance, especially if the difficulty is in recruiting workers for highskilled positions, with the relatively low marginal cost and institutional rules increasing the probability of workers offered health insurance in positions outside the one in which the compensation is negotiated. Our analyses of firm and job-level data in the CHES support these arguments. We find that a 20 percentage point increase in the percentage of high-skilled workers in the firm – roughly the percentage difference between our samples of low- and high-skilled jobs – produces a four percentage point increase in the probability of a firm offering health insurance. We also show a 13 percentage point increase in the probability of a firm offering health insurance if it has difficulty recruiting in high-skilled positions and a 5.7 percentage point increase with recruiting difficulties in low-skilled positions. When we compare the recruiting difficulty in the job for which compensation is negotiated (market forces) with the recruiting difficulty in positions other than the one in which compensation is negotiated (rules and economies of scale), we find a larger increase in the probability of an offer when difficulties arise outside the area of compensation negotiation, as long as the difficulty is in mid- or high-skilled positions. Recruiting difficulty in positions in which compensation is being negotiated increases the probability of offering health insurance by about five to six percentage points, irrespective of the skill position level with the percentage increase about 10–13 points if the difficulty is in mid- or high-skilled positions other than the one in which compensation. One critical insight from this study is that it draws attention to the consequences that rules and economies of scale play in influencing a firm to offer health insurance. The relatively high fixed cost that a firm bears in offering insurance and decreasing marginal costs that it faces may create inframarginal decision making in offering fringe benefits and move the tradeoff with wages away from the individual level. Once the decision to
108
NAN L. MAXWELL
offer benefits is made, the low marginal cost of extending the offer to additional workers may negate a tradeoff with wages for many workers, particularly those that do not value the benefit, which presents problems in empirical establishing a wage-health insurance tradeoff (for example). By focusing on firm behavior in light of these considerations, our research shows how including factors that affect the probability of a firm’s offering health insurance, but not necessarily its tradeoff with wages at the individual level, helps to reduce the positive empirical relationship that has plagued microlevel analysis of the wage and health insurance tradeoff. Inframarginal decision making might be attractive from a policy perspective if it decreases the number of uninsured. If rules and economies of scale create incentives for firms to offer health insurance to low-wage workers who value the offer less than the equivalent offer of wages, the number of uninsured might be decreased. Such workers might not take up health insurance without the heavy subsidy of premium that an employer often pays and might not take a job offer if wages were lowered by the cost of insurance. Because rules and costs might provide firms with an incentive to extend an offer of insurance to such workers without reducing wages, a greater proportion of the population might be insured. The underlying impetus for the ACA extending the nondiscrimination rule to virtually all employer-based plans (allowing for some grandfathering) was likely grounded in such reasoning. Alternatively, extending the nondiscrimination rule may increase a firm’s fixed cost of offering insurance, if the third-party insurers requirements for structuring the offer are less stringent than the nondiscrimination rule. Under such circumstances firms that do not offer insurance will bear higher start up costs in making an offer and some firms might face the possibility of dropping insurance with elevated costs. We leave to future research the question of which effect is strongest.
NOTES 1. A self-insured plan is one in which the firm acts as its own insurer and bears the risk of providing health coverage for insured events, even if the employer contracts with an insurance company to administer the plan. In contrast, fully insured plans are ones in which the firm pays a per-employee premium to a third party (insurance company), who then assumes the risk of providing health care for insured events. Before the ACA, Congress restricted the nondiscrimination rule to self-insured plans. 2. Benefits received through a cafeteria plan are taxed because they are deemed to be in constructive receipt of the cash unless the plan meets various reporting and nondiscrimination requirements (Lyke, 2006).

3. The nondiscrimination rule provides several ways in which a firm can discriminate. It can establish separate plans for distinct classes of large groups (more than 50 employees) with a business rationale (e.g., hourly and salaried), although explicit grouping by compensation level is not allowed. It can also exclude certain workers from the rule (e.g., less than three years of tenure, under age 25, part time or seasonal, and under a collective bargaining agreement). Carrington et al. (2002) provide a discussion. 4. Insurers typically do not assess risk in firms with 500 or more workers but rate the smallest firms individually for risk, just as in the nongroup (individual) market, because a single sick employee with a high utilization level could inflict a loss on the insurer (Cutler, 1994). 5. All workers pay taxes on wages but not health insurance. However, workers with a 35 percent marginal rate face greater tax savings from tax-free benefits than workers with a 5 percent marginal rate. Pauly (2001) provides a succinct overview. 6. See RAND’s Health Insurance Experiment (Newhouse, 1993) and the natural experiment with mandated maternity benefits (Gruber, 1994). 7. The sampling frame for the data was establishments with multiple establishments in the same firm not included. 50.5 percent of the samples are single-establishment firms. We discuss the data as if the firm were the unit of analysis because health benefits were virtually all set by the firm, not the establishment. Only 62 establishments in multi-establishment firms (4.3 percent) report setting their own benefits. 8. Such analysis overstates the decision making of larger firms with their greater employment. 9. Respondents were asked ‘‘about the different types of positions you have (in the establishment). We are particularly interested in learning about positions requiring different levels of education and work experience. In answering these questions, we would like you to think about ALL the positions in this firm at this location and to classify them by the education and training level required of workers when they start the job.’’ 10. Firm size categories were structured such that firms could be delineated as to whether they were subjected to the rules governing the small group health insurance market in California (2–50 employees) (Roth, 2003). 11. Respondents used a four-point scale to assess their ability to attract workers with the needed skills. Jobs classified as ‘‘a little hard’’ or ‘‘very hard’’ to attract needed skills were categorized (¼1) as hard to attract skills in job. 12. Appendix Table A1 provides an empirical definition for each measure. We included county level unemployment in estimations as an additional control for county level differences. Estimated coefficients were virtually identical to those presented in our tables and the variable gained significance (at pr0.05) only in the ‘‘Traditional Model’’ and the ‘‘Mid-Skilled Jobs’’ model presented in Table 3. 13. The question asked ‘‘$____ per _____’’ (e.g. $9.85/h). We assumed full-time work when computing hourly wages for responses not reported as hourly in the raw data, (e.g., annual salary was divided by 2080, monthly salary was divided by 173, and weekly was divided by 40). About 92 percent of wages in low-skilled jobs were reported as hourly, compared to about 80 percent of mid-skilled jobs and 52 percent of high-skilled jobs. Conversely, about 42 percent of wages in high-skilled jobs were reported in annual salary, compared to about 19 percent in mid-skilled and 8 percent
110
NAN L. MAXWELL
in low-skilled jobs. Surveyors were instructed to remind respondents that the questions pertained to ‘‘when [workers] start the job’’ when asking the question about average wage in the job at skill position level. 14. We confirm the OLS results with marginal effects estimated through probits (see appendix Tables A2 and A3). We present the OLS estimations because the probits estimated for the high-level jobs do not produce stable estimates of the coefficient on the union variable. Only 72 of the high-skilled firms do not offer health insurance and none of them are unionized (over 90 percent are for profit). Because unionization is too central to the literature on the firm offering health insurance to drop it from the model, we report the OLS estimations. 15. Firms with a higher percentage of high-skilled workers may have low-skilled workers who are of higher quality in unobservable ways, thus are receiving health insurance for that reason. We cannot identify these potential quality differences with the broad education categories used to define high- and low-skilled workers. 16. Difficulty in hiring might be correlated with the type of workers sought, with workers at the high end of the skill distribution harder to recruit at all levels of the skill distribution.

MAJORITY OWNERSHIP AND CHIEF EXECUTIVE COMPENSATION Derek C. Jones and Niels Mygind ABSTRACT In this chapter, we provide the first empirical study of the effects of differing types of majority ownership, including employee ownership, on executive compensation. By investigating the case of Estonia, we also extend the range of geographical coverage of studies of the determinants of executive compensations to the case of Estonia. Although previous research finds that the type of ownership affects CEO pay, our new panel data, and the exceptional configurations of ownership that prevailed in Estonia during early transition, enable us to construct unusual measures of majority ownership. Findings indicate that an economically significant determinant of CEO pay is ownership both in state versus privatized firms and in different types of private firms. In firms with majority ownership by employees, pay is about 15% less than in state-owned firms, other things equal. CEO pay is also positively related to size and seldom related to performance although size elasticities are much smaller than those estimated in other studies, mainly for advanced western countries.

Findings provide more general support than previously for the varying importance of principal–agency relationships across firm types and the views that privatization and employee ownership have imposed strong discipline on the level of CEO compensation. Keywords: Executive compensation; ownership structures; employee ownership; privatization; Estonia JEL classifications: J3; P00; I2
INTRODUCTION A recent survey (Frydman & Jenter, 2010) of the often highly charged subject of executive compensation notes that most early empirical work concentrated on the United States. The range of more recent empirical work has broadened substantially with studies including most developed market economies and some emerging economies. Perhaps surprisingly, apparently only two studies exist for the former Soviet economies, namely, Jones and Kato (1996) for Bulgaria and Eriksson (2005) for the Czech Republic. In this chapter, we extend geographical coverage by providing the first empirical paper on executive compensation in Estonia. Our focus is on the consequences of different ownership arrangements for executive pay. Theorists predict that differences in ownership and organizational structure will be accompanied by variation in monitoring and incentive-alignment mechanisms with conflicting views on the role of managers’ ownership in affecting enterprise performance (e.g., compare Demsetz & Lehn, 1985; Jensen & Meckling, 1976). However, empirical work on propositions concerning ownership is limited in large part reflecting a narrow range of ownership structures in western economies. The available empirical work tends to focus on matters such as the effects of varying amounts of insider ownership on CEO pay and performance (e.g., Morck, Schleifer, & Vishny, 1988).1 Investigations of the effects on executive compensation of differences in majority ownership are quite scarce. Moreover, they tend to examine outcomes only for managers and make comparisons with benchmark conventional firms that have dispersed ownership. For example, Denis and Denis (1994) use data for US firms to investigate the links between majority ownership by managers and organizational efficiency.2
Majority Ownership and Chief Executive Compensation

The disintegration of the former Soviet economies led to adaptations of principal-agent theory to that case (e.g., Boycko, Schleifer, & Vishny, 1996). Among transition cases, the early Estonian experience was especially interesting because privatization produced a broad array of ownership types. In nearly all firms, a clear majority owner usually was apparent, and these differing majority ownership forms coexisted for several years. Thus, for a large stratified random sample, Jones and Mygind (1999) found that, in 1997, each of the following five groups were majority owners in at least 10% of sample firms – nonmanagerial employees, managers, foreigners, domestic outsiders, and the state.3 This ability to classify Estonian firms on the basis of majority ownership enables us to examine whether type of majority ownership is associated with CEO pay. Moreover, in recent years, some researchers (e.g., Bebchuk & Fried, 2004) have argued that executive compensation is most fruitfully examined through the lens of managerial power. It would seem that this theme is especially useful to examine during early transition, when insiders, notably managers, accumulated enormous power (e.g., Estrin, Hanousek, Koc, & Svejnar, 2009). The standard executive compensation literature identifies key roles for size and enterprise performance in influencing CEO pay and also provides benchmark estimates of their economic importance (e.g., Murphy, 1999). It is instructive to see whether size and performance play similar roles in Estonia during early transition and thus help to gauge the extent to which the managerial labor market functioned during early transition.4 After briefly reviewing key issues in the theoretical and empirical executive pay literature, we then relate some of these issues to the specific context facing former Soviet-type economies during early transition. After outlining basic aspects of the privatization process and transition in Estonia, we describe our unusual data – a representative panel of firms with corresponding data at the chief executive level. After outlining the empirical strategy, we report findings from our fixed effects models.
CONCEPTUAL FRAMEWORK There is an extensive literature that predicts that differences in corporate ownership are expected to have links with firm performance and valuation including systematic relationships between ownership structure and pay (Frydman & Jenter, 2010; Murphy, 1999). In the main, this literature is concerned with publically held firms in which most ownership is held by outsiders (individuals and institutions that do not work in the firm) and in
118
DEREK C. JONES AND NIELS MYGIND
which firms are assumed to focus on profitability and maximizing shareholder value. Much of this literature has concentrated on the effects of relatively limited differences in ownership by senior managers and how agency costs might be ameliorated by modest amounts of ownership by managers (e.g., Jensen & Meckling, 1976). By contrast, relatively little attention has been devoted to CEO pay in different types of firms and in which firms might pursue varying objectives.5 However, there are various reasons why CEO pay is expected to be different when firms are of quite different types. Consider firms in which the state is the majority owner (as remains the case in some firms in former communist countries, even after more than 20 years of transition). Some have argued (e.g., Aslund, 1999) that rent-seeking by managers in large state-owned firms can be expected to be more important than in privatized firms that are far less politicized and in which market forces will be expected to exert more discipline on CEO compensation.6 In addition, the special circumstances that confronted firms during early transition in former Soviet-type economies arguably introduce additional considerations that potentially exert greater force in firms that remained in the state sector. In an economy such as Estonia, in which hard budget constraints prevailed quite early in the reform process (OECD, 2000), the prediction of a strong link between executive pay and performance might be expected to be stronger than in countries with less financial discipline. At the same time, the link is expected to be strong only if several other conditions were met including the existence of an active market for managers with a requirement that managers and other economic agents are well informed of comparative firm performance. When such assumptions are not met, the pay–performance link may be expected to be quite weak, as might be the link between size and performance for firms that started transition with bloated levels of employment. These links are expected to be especially weak in firms in which firm objectives moved only slowly away from objectives that flourished under Soviet-type arrangements. For example, while for many private firms, profits soon became the dominant goal during early transition; in many state firms, a higher value was likely to continue to be placed on other objectives such as employment stability. Furthermore, during early transition, the managerial labor market might display institutional legacies from Soviet times; managerial pay was apt to be a base wage and top managers would be paid a low multiple of the average wage. Theorists have pointed out how these arrangements would be expected to result in acute incentive and motivational problems for
Majority Ownership and Chief Executive Compensation
119
managers (e.g., Bonin, 1976). A substantial gap would emerge between behavior in a proprietary fashion (as called for under the official ideology) and the reality of risk aversion and the pursuit of a quiet life (Kornai, 1992). Partly because of asymmetries in information between managers and planners, a ‘‘ratchet effect’’ would emerge with extensive managerial slack (e.g., Ickes & Samuelson, 1987). In turn, several systemic inefficiencies were predicted (e.g., Putterman, 1993). Hence, to facilitate successful overall reform during early transition, many stressed the crucial importance of reforming incentive systems (e.g., Aghion, Blanchard, & Burgess, 1994). A need existed to structure executive pay to provide pecuniary incentives for managers to pursue profitability and encourage more market-oriented managerial behavior. At the same time, the historical legacy and institutional inertia would act as a drag on the reform of executive pay systems. These forces might be expected to be stronger in firms that remained in the state sector and far weaker in firms in which new forces were more clearly evident, as in many privatized firms. As well as predicting differences in CEO pay between firms in the state versus the private sector, differences in the forces influencing CEO pay are also expected to vary according to the type of private ownership. For western firms, to the extent that this issue has been engaged, the literature has concentrated on agency costs and the effects of relatively limited differences in ownership by senior managers. The early literature (e.g., Jensen & Meckling, 1976) suggests that managerial ownership might be beneficial for firms helping to better align the interests of managers with those of dispersed outside shareholders. But later work argued that considerable costs were thought to be associated with large managerial ownership stakes with powerful managers entrenching themselves, obstructing board monitoring activities, and introducing policies (including excessive compensation) that benefit themselves (Bebchuk & Fried, 2004). Hence, while principal–agency problems might be resolved by majority ownership by senior managers, reflecting these differing perspectives, nonmanagerial shareholders might either benefit from or suffer under majority ownership by managers. A theoretical literature also examines the relationship between ownership by outsiders (especially by institutions) and managerial pay. Again there appears to be theoretical ambiguity as to outcomes (e.g., Pound, 1988). If there are strategic alliances between institutions and managers, then firm performance might suffer and be accompanied by managers receiving excessive pay. Alternatively, if outside institutions effectively monitor managers, then shareholders will benefit (and presumably managers will not
120
DEREK C. JONES AND NIELS MYGIND
receive excessive compensation).7 In the case of firms in which there is majority ownership by foreigners, similar considerations might be expected to apply. Thus, to provide for improved monitoring of managers, firms owned by foreigners can be expected to be more likely to pay higher (efficiency) wages and to link pay with firm performance. This will contrast with firms that are owned by employee insiders who, because of closer proximity, are able to closely monitor executive performance and who will be expected to be more effective at disciplining managers than in other private firms. Finally, it is worth noting that not all who predict differences in CEO pay by type of private ownership focus on principal–agency relationships; moreover, the predictions of other theorists may sometimes differ from those who emphasize principal–agency issues. Thus, theorists who reason from a more comparative organization perspective stress that differences in ownership are also likely to be associated with differences in enterprise objectives and thus managerial rewards and the types of managers wanted by different kinds of organization. The case of employee ownership is especially pertinent. The greater likelihood of employee-owned firms having differing value systems and institutional practices such as mechanisms for employee participation in decision making (Hansman, 1996) can be expected to produce more compressed wage structures – lower levels of executive pay – than in firms with other forms of majority ownership.8 This argument is especially pertinent in those former Soviet-type economies such as Estonia where egalitarian norms were strong in the past (Mygind, 1999) and where, because of institutional inertia, such norms could have been expected to continue to exert an influence on pay structures during early transition. In addition, employee-owned firms may be expected to place a greater emphasis on goals other than profits and on outputs that are more difficult to measure and reward. In turn, this pursuit of different objectives produces differences in the kinds of managers required by employee owners and also in the importance of non-pecuniary rewards to managers in such firms (Frey, 1997).
PRIVATIZATION AND TRANSITION IN ESTONIA As our econometric work hinges on differences in ownership structures, it is important to consider key aspects of the legal institutional changes that occurred in Estonia during early transition. In Estonia, often privatization is discussed (e.g., European Bank for Reconstruction and Development
Majority Ownership and Chief Executive Compensation
121
[EBRD], 2000) as though all privatization had occurred in a particular way (through a state agency soliciting tenders for state firms). But in fact, the privatization process has been much more complex and the resulting range of forms of enterprise potentially is quite diverse. In Estonia, as in many other transition economies, initially the privatization process conveyed special advantages to insiders. This happened first during the Gorbachev era in the late 1980s with the nurturing of a handful of collectively owned firms or ‘‘people’s enterprises.’’9 Subsequently, there were opportunities for employees to lease state firms, and initially, some advantages were given to employees concerning privatization of small firms. However, these advantages to employees were short lived (Kalmi, 2002). The objectives of privatization legislation changed away from limited support for employee ownership. A political climate, which altered dramatically after independence, led to the bulk of the privatization of big firms proceeding through use of a Treuhand-like privatization agency soliciting tenders for state firms. Equally, a core investor model was encouraged and foreign ownership was aggressively and fairly successfully sought (OECD, 2000). Consequently, after 1993, very few firms were privatized to employees. However, reflecting earlier privatization policy, it is likely that very different patterns of ownership might have been expected to have emerged within Estonia. But the situation is complicated because both theory and case studies (e.g., Kalmi, 2003) suggest that these new forms of ownership varied in stability. In particular, employee ownership is believed to have been much been less stable than other forms of ownership (e.g., Aghion & Blanchard, 1998; for Estonia, Jones & Mygind, 2005). Also, case studies of firms privatized early do not provide any strong evidence of any selection bias insofar as employees were systematically able to buy firms that were better performing than the average firm (Mygind & Pedersen, 1996). Finally, when examining the determinants of executive pay in Estonia, it is useful to take into account a number of features of transition in that country. According to many macro-economic indicators, early systemic performance in Estonia was far better than most former communist countries (Estrin et al., 2009). Second, the Estonian transition strategy included rapid price and trade liberalization and a new competition policy, and thus is reminiscent of ‘‘big bang’’ experiences elsewhere. Also, the move to privatization of large state-owned firms was quite rapid and was quite advanced during the period under study in this chapter. In these respects, the Estonian situation is very different than that prevailing in other
122
DEREK C. JONES AND NIELS MYGIND
transition and developing countries where CEO compensation has been examined.10 Thus, during early transition in Bulgaria, a focus of reform efforts was on corporatization rather than wholesale privatization. Perhaps, most important, because of the failure to deal with the problem of bad debts, the context within which Estonian managers operated was nearly always characterized by hard budget constraints – a very different situation than that which confronted managers of, for example, corporatized firms in Bulgaria, and more akin to that confronting managers of Czech firms (Eriksson, 2005).
DATA With the cooperation of the central statistical authority, annual economic and financial data were extracted from the population of Estonian companies that existed during 1993–1997 to produce a random sample of 666 firms. This rich panel contains standard economic data, including profits, sales, assets, and employment.11 However, because this data set has limited information of enterprise ownership and CEO characteristics, it was necessary for the authors to administer two special surveys and then to merge the resulting data sets. One survey focused on the distribution of ownership and aimed to collect annual data during 1993–1997 from all firms in this large panel. Reflecting influential literature (e.g., Aghion & Blanchard, 1998), the focus was on ownership by insiders (gathered separately for managers and employees) and non-state outsiders (split into foreigners and domestic owners) as well as ownership by the state.12 By selecting a large sample, we expect to have representation of firms in which these different owners assume varying importance and including some firms that were never privatized. The response rate for this ‘‘ownership survey’’ was very high – more than 95%. The other survey collected data for a random subsample of top executives in 220 of these firms, including information on their compensation packages.13 As CEO compensation data are not publically available in Estonia, we must rely on survey data to obtain this information. At the same time, several factors including the small size of the Estonian economy and traditions of openness concerning managers’ pay packages mean that we are confident that our data on CEO pay are reasonably accurate. Indeed in several cases, we were able to cross-check the self-reported data (through informal channels), and in all of these instances, we found no major discrepancies between the numbers reported using the different sources.
Majority Ownership and Chief Executive Compensation
123
In sum, we have no reason to believe that there are major measurement problems with any of our key variables. These data enable not only estimation of diverse specifications but also construction of measures of key variables. Concerning ownership, most studies of executive compensation in transition economies have been able to attempt to classify firms according to whether firms are state or privately owned. And even though there has been a huge amount of literature that investigates the impact of different forms of privatization upon economic performance (reviewed in Djankov & Murrell, 2002; Estrin et al., 2009), usually they are able to construct measures only of which group is the largest or the dominant shareholder (Frydman, Gray, Hessel, & Rapaczynski, 1999). However, for several reasons, this procedure does not necessarily produce the preferred typology of ownership forms. For example, dispersed shareholdings within a category may lead to limited cohesiveness by the dominant ownership group, which may account for as little as 25% of the total voting stock. However, in most cases in Estonia, the available data mean that we are able to classify firms based on the analytically preferable method of majority ownership. In Table 1, we are able to classify 214 (of 220) firms according to their majority ownership status in all years during 1993–1997, although here we report these data only for the first and last years. One important fact concerning the nature of ownership among Estonian firms is that, during this period, there was enormous dispersion in ownership types. Although there have been instances in other economies in which some of these types of majority ownership have assumed prominence, it is most unusual, even

among transitional economies, to find such high proportions for some of these types of firms. Thus, by 1997, in more than 27% of firms, managers had assumed majority ownership, about double the highest rate for other transitional economies for which data are available then.14 Moreover, in most other transitional economies, there tends to be a particular pattern of majority ownership that tend to emerge after privatization – for example, in the Czech Republic firms that were majority-owned tended to be mainly owned by investment funds. But in Estonia, Table 1 indicates a remarkable tendency for several types of majority ownership to coexist and instances in which there was not a majority ownership group are very rare.15 Table 1 also indicates that dramatic changes in ownership occurred during the period.16 In Table 2, we present descriptive information on key economic variables.17 By examining the entries for the whole sample, we see that, on average, during 1993–1997, real monthly CEO compensation fell very slightly, as did size when measured by sales. However, when measured by employment and assets, size fell much more sharply. For the whole sample, all performance measures – labor productivity, return on assets, and profits – deteriorated sharply.18 Another purpose of Table 2 is to present descriptive information according to type of majority ownership. As majority ownership status changes in many firms during the period, we classify firms according to their ownership status at the end of the period (in 1997) and then make comparisons with how this group was doing at the start (in 1993). Thus, the entries for majority state-owned firms (in both 1993 and 1997) are obtained for those 11 firms that were majority state-owned in 1997. Table 2 reveals great differences in key variables when firms are classified according to majority ownership and that often these vary by ownership type. Firms that remained state-owned throughout the period continued to be much larger than other firms, although their rate of shrinkage was noticeably faster than for other firms.19 Unlike other firms, they also experienced rapidly increasing losses during 1993–1997. CEO pay in state firms suffered enormously too while performance indicators displayed an uneven record – for example, compare constant labor productivity and declining margins. In private firms, pay differences between managers and the average worker (RATIO) typically were quite modest – about 3:1. Interestingly, during 1993–1997, this ratio fell in foreign-owned firms (as well as in employee-owned firms), although it widened somewhat in other private firms. 20 However, the level of CEO pay was much higher in 1997 in firms majority-owned by foreigners – more than three times as high as in firms in which employees were majority owners. Unlike firms owned by mangers or

domestic outsiders, real CEO pay in foreign-owned firms (which includes firms that were always foreign-owned as well as firms that became foreignowned) fell during 1993–1997. Performance indicators for private firms were typically stronger than in state firms although patterns varied by majority ownership type. Thus, for firms that were majority foreign-owned at the end of the period, sharp gains in real sales and in profits were recorded, although labor productivity declined considerably. Although productivity and sales grew in employee-owned firms, profits fell. In firms owned by managers, profits, margins, and the return on assets all improved although sales fell and productivity stagnated. Typically foreign-owned firms experienced greater rates of contraction (especially in employment) than did other privately owned firms.
THE RELATION BETWEEN EXECUTIVE COMPENSATION AND FIRM PERFORMANCE IN TRANSITION To study the determinants of the level of CEO pay, in the first set of regressions, we augment a standard chief executive compensation equation21 by a dummy variable indicating whether, during the period 1993–1997, the firm remains state-owned. That is, ln Payit ¼ b lnðSIZEit Þ þ ðPERFORMANCEit Þ þ ðSTATEit Þ þ 8i þ Wt þ uit
(1) where Payit is chief executive pay of firm i in year t; SIZEit is size of firm i in year t; PERFORMANCEit is standard firm performance measures such as various accounting profitability measures of firm i in year t; STATEit ¼ 1 in years in which a firm is state-owned, 0 otherwise; ’i is firm-specific fixed effects; and Wt is year effects. The disturbance term, uit, is distributed NID(0, F2). To examine hypotheses on the impact of the type of private ownership, in the second set of regressions, we estimate Eq. (1)* where we replace STATEit in Eq. (1) by a set of four majority (private) ownership dummies (where the base case is majority state ownership).22 PERFORMANCE and SIZE have been included in prior empirical studies of executive compensation in advanced market and transitional economies. In the western literature, the application of principal–agent theory to the design of executive contracts in general predicts a positive correlation between managerial pay and some observable measure of firm
Majority Ownership and Chief Executive Compensation
127
performance (which eventually translates into improved well-being for shareholders).23 To adequately measure PERFORMANCE, the debate has usually centered on the respective merits of measures of stock market returns compared to various accounting measures such as ROA (the return on assets). However, in a context of embryonic capital and stock markets (as in Estonia during this period), this debate is moot. Moreover, many have argued (e.g., Earle & Estrin, 1998) that the key performance measure may be labor productivity. Thus, in our empirical work, as well as two accounting measures, ROA and MARGIN (gross profit/sales), we also consider labor productivity as an alternative firm performance measure. SIZE is included in western studies because theory stresses the importance of factors such as spans of control in determining CEO pay. For transition economies, being a chief executive of a firm with many employees under communism often translated into more political power and thus an improved ability to obtain higher pay. To see if this force persists, our data allow us to use three alternative SIZE measures: (i) EMPLOY (number of workers); (ii) SALES (in 1993 real kroons); and (iii) ASSET (total assets in real 1993 kroons). In all estimates, we use a two-way fixed effects model. Year dummy variables (Wt) capture technological change and other shocks common to all firms as well as possible measurement errors of inflation. Firm-specific effects (’i) are included to capture time invariant firm-specific factors that may affect chief executive pay.24 We estimated nine specifications of Eq. (1) depending on the selection of the size and performance measures.25 Importantly, for all specifications reported in Table 3, F-tests refute the joint exclusion of year dummy variables and firm-specific fixed effects at the 1% level. The first three columns of Table 3 summarize the results when employment is used as a size measure, whereas columns 4–6 report findings using sales as a measure of size and in the last three columns assets are used to proxy size. For each size measure, results are reported when the three different performance measures are used (for example, ROA in columns 2, 5, and 8). Finally, all models include a dummy variable for whether or not the firm was state-owned in that year. We begin by examining the impact of ownership on CEO pay. From Table 3, we see that the ownership coefficients are statistically significant (10% or better) in six cases and close to being statistically significant in the remaining cases. This is reasonably strong evidence that whether a firm is privately or state-owned matters much in the determination of CEO pay, and CEOs in state firms earn higher pay then their private counterparts,

even after controlling for size, performance, and other time invariant unobservables. These positive and significant estimates suggest that, after controlling for firm performance, the average CEO working for a stateowned firms receives additional rents of 10–13.6% as compared to his/her counterpart in privatized firms. Furthermore, the comparative magnitude of these ownership coefficients are quite large – for example, a doubling of employment would be expected to produce only about a 5% increase in executive pay, which is far less than the effect of an ownership change. Hence, the rent earned by state firm CEOs seems to be significant not only statistically but also economically. Put another way, the positive and significant estimates on the coefficient of STATE might be interpreted as indicating the presence of financial discipline, which privatization has brought to CEO compensation, at least in privatized firms during early transition.26 No matter which measure of SIZE is used, evidence is found of a positive relationship, and eight of nine SIZE coefficients are statistically significant. Although results are not sensitive to the choice of the PERFORMANCE measure, the estimated pay elasticities of size are quite small and in the range of 0.03–0.08. For example, as sales increase by 10%, CEO pay increases by 0.3–0.5%; for assets, the comparable effect is 0.8%. These elasticities are much smaller than those obtained in other studies. For example, Rosen in reviewing various western studies on the estimated elasticity of pay with respect to scale finds a typical value of 0.25, whereas Jones and Kato (1997) report elasticities of size of 0.2–0.4 for Bulgaria. Finally, there is mixed support for the existence of a relationship between CEO pay and PERFORMANCE. For productivity (ln PROD), no statistically significant relationship is ever found. However, when ROA is used to proxy performance, as hypothesized, the relationship is always found to be positive, and in one case, it is also statistically significant. Also, in two of three cases, evidence is found of a positive and statistically significant relationship between PERFORMANCE (measured by MARGIN) and CEO compensation. Again, these elasticities are smaller than those obtained in other studies. Thus, Rosen finds that the estimated sensitivity of pay to accounting measures are in the 1.0–1.2 range, about twice the size of the estimated semi-elasticities for Estonia for ROA. However, the finding of statistically significant relationships between PERFORMANCE (measured by ROA or MARGIN) contrasts with the case of Bulgaria where the only significant link was when productivity was used. This finding of a weak link between pay and performance is not unexpected. It suggests that conditions that will better facilitate managers

being able to give improved attention to comparative business performance had not yet been provided been during early transition. In Table 4, we report our estimates of Eq. (1)* (when we explicitly examine the impact of the particular form of private ownership). In light of F-tests on the equality of the coefficients on the ownership dummy variables, the specifications reported in Table 4 are preferred to the corresponding specifications reported in Table 3.27 Importantly, in all nine estimates, separate F-tests refute the joint exclusion of year dummy variables, the vector of private ownership dummies, and the firm-specific fixed effects at the 1% level. First, we discuss findings for different forms of individual ownership. The most consistent evidence emerges when employees are majority owners. As hypothesized, relative to firms in which the state is the majority owner, firms with majority employee ownership pay their managers less, other things equal. Employee ownership coefficients are statistically significant for eight (of nine) specifications, and the size of the ownership effects is remarkably consistent across all specifications, averaging about 15%. This finding provides strong evidence for the hypothesis that, because of their close proximity, employee insiders monitor executive performance and CEO pay and thus avoid some agency costs. However, the evidence is also consistent with the view that, compared to other firms, employee-owned firms place a greater emphasis on goals other than profits (such as income equality) and on outputs that are more difficult to measure and reward. In turn, this pursuit of different objectives produces differences in the kinds of managers required by employee owners and in the importance of non-pecuniary rewards to managers in such firms.28 More surprisingly, perhaps, CEOs in firms in which domestic outsiders are the majority earn less than counterparts in state-owned firms. This relationship is strongly statistically significant in four of nine specifications and quite close to being statistically significant in remaining specifications. The effect ranges from 9 to 12% depending on specification. This evidence is consistent with the hypothesis that external owners are monitoring managers and helping to ensure that CEOs do not receive excessive compensation. As hypothesized, firms in which ownership lies overseas always pay their managers more although these effects are never statistically significantly different than zero (although t-statistics are usually quite a bit higher than one). Thus, these estimates, at best, provide very weak evidence in support of managers of foreign-owned firms receiving efficiency wages. Finally, once controls for size, performance, and time invariant firmspecific factors have been introduced, it appears that the level of CEO pay in

firms owned by managers is no different than in firms owned by the state. All managerial ownership coefficients are quite tiny and strongly insignificant. As such, this evidence of the absence of excessive compensation for CEOs in managerially owned firms provides strong evidence for the view that managerial ownership, even at very high levels, can convey benefits to firms and minority shareholders.29 As in the previous estimates reported in Table 3, again we find that most measures of SIZE in Table 4 have positive and statistically significant effects on the level of CEO pay, other things equal. The sizes of the coefficients on the three proxies for SIZE are essentially unchanged from the previous estimates. However, and unlike findings reported in Table 3, in these estimates, we find that PERFORMANCE is never statistically significant.30 Thus, this evidence strongly suggests that the conditions that will better facilitate managers being able to give close attention to relative business performance had not yet been developed during early transition.
SUMMARY AND IMPLICATIONS By using unusual panel survey data for Estonian firms with matching information for chief executives, we study the determinants of the level of CEO compensation during early transition. As privatization led to the emergence of firms with sharply differing majority ownership configurations, we were able to examine the potential role of large differences in enterprise ownership as well as traditional forces, such as size and performance. Findings based on fixed effects models indicate that CEOs in state-owned firms receive about 10–12% more pay than CEOs in private firms, ceteris paribus, which is quite sizeable. Moreover, we find that an economically significant determinant of CEO pay is ownership. The most consistent findings are for firms in which employees are the majority owners; relative to firms in which the state is the majority owner, firms with majority employee ownership pay their managers about 15% less, other things equal. CEO pay is also found to be statistically lower (by about 10%) in firms owned by outsiders who are not foreigners. But in firms owned by foreigners or managers, no statistically significantly differences are found (compared to CEO pay in state firms). However, we are aware that our findings are potentially limited by some limitations of the data. In particular, we are unable to include individual CEO fixed effects. It is certainly plausible that managers could change during this period of early transition (and that new compensation contracts could be formed during transition). At the same time, we note that often
Majority Ownership and Chief Executive Compensation
133
when managerial turnover has been included in managerial performance– pay regressions in other transition economies, results do not seem to be strongly affected (e.g., Eriksson, 2005). Also we are aware that there are potential econometric issues surrounding ownership and endogeneity. It is possible that highly paid managers influence ownership type and that complications may arise from non-salary types of compensation or actual ownership holdings of top managers. Unfortunately, the available data do not enable us to address such matters in a satisfactory way (e.g., there do not appear to be suitable instruments to enable instrumental variable estimates). Subject to these potential limitations, the finding that ownership, including the particular form of ownership, has important effects for the level of CEO pay potentially has broad implications. Previous research on the determinants of executive pay has established that institutional arrangements do have economic consequences. For example, concerning ownership by top managers, Holderness and Sheehan (1989) provide examples of excessive compensation (although Ang, Hauser, & Lauterbach, 1997 do not uncover similar evidence). Also, there is evidence that different managerial labor markets exist for firms with different objective functions – for example, Roomkin and Weisbrod (1999) find that monetary compensation is substantially higher in for-profit hospitals than in nonprofits. But our findings are for a case where extraordinary differences in ownership structures and institutional conditions existed and thus enable much more general tests of such propositions to be undertaken and more general conclusions to be drawn. Thus, concerning ownership, a large body of work (e.g., Estrin et al., 2009) and including the particular case of Estonia (Jones & Mygind, 2002) points to the benefits of privatization for improved business performance. The evidence presented in this chapter clearly reinforces the conclusion that there are benefits of privatization. It appears that the arrangements that existed in privately owned firms in Estonia enabled all types of privately owned firms to do a better job of monitoring CEO pay than was possible under the institutional arrangements that existed in state-owned firms and which enabled CEOs to continue to engage in rent seeking.31 Findings on the links between the form of private ownership and CEO pay provide evidence that relates to diverse hypotheses. Thus, the finding that CEO pay in firms owned by managers was not excessive (relative to state-owned firms or foreign-owned firms) provides strong evidence for the view (e.g., Jensen & Meckling, 1976) that managerial ownership, even at very high levels, can convey benefits to firms and shareholders. However, in some cases, our findings are consistent with more than one hypothesis. In particular, our finding that CEO compensation is significantly lower in
134
DEREK C. JONES AND NIELS MYGIND
employee-owned firms is consistent with the principal–agency story that employee owners are able to reduce agency costs by effectively monitoring managers. But this evidence is also consistent with the view that employeeowned firms pursue different objectives than other firms. This produces differences in the kinds of managers required by employee owners and also in the importance of non-pecuniary rewards to managers in such firms. Finally, arguably, our findings do not provide evidence that, from the perspective of CEO pay, there is an optimal form of private ownership. As such, this conclusion mirrors much of the evidence that examines links between types of private ownership and enterprise performance. Simultaneously, we investigated the role of more traditional determinants of executive pay during this interesting period of early transition. These findings indicate that CEO pay is always positively and usually statistically significantly related to variation in size, which is measured by sales, assets, and employment. The evidence on the link between CEO compensation and performance is much more mixed. Using measures such as profit margin and ROA, evidence of a positive and statistically significant relationship is sometimes found when estimates include only a single ownership dummy (indicating whether a firm is privately owned). However, in the preferred specifications, when we introduce several ownership dummies reflecting differences in types of majority private ownership, no link is found between pay and productivity. Together with the strong compensation–size link and the very weak pay– performance relationships, our findings on the importance of ownership for CEO pay suggest that the financial discipline surrounding firms in the Estonian state sector was especially weak during the period under investigation. In other words, arguably, privatization has imposed strong discipline on the level of CEO compensation in Estonia. However, compared to findings from other studies, the size and performance semielasticities typically are quite small, averaging about 0.04 and 0.06, respectively. These findings suggest that executive compensation in Estonia is set so as to provide only weak incentives for managers to pay limited attention to firm size and almost no attention to current business performance. This finding of a weak link between pay and performance has been found in other transition economies, including Bulgaria (Jones & Kato, 1996) although Groves, Hong, McMillan, and Naughton (1995) find a strong pay–performance link in China. In accounting for the differences across countries on these points, clearly, the differences in institutional contexts matter. In addition, the failure to find a link between productivity/ profitability and pay in Bulgaria is unsurprising because, unlike in China,
Majority Ownership and Chief Executive Compensation
135
the performance of the Bulgarian economy has been so chaotic. But the existence of a very weak pay–performance link in Estonia, especially during a period when it is believed that Estonian firms operated under hard budget constraints, is more difficult to explain. Finally, our finding of the strong role played by employee ownership in limiting executive pay is potentially of interest to policy makers who seek mechanism to rein in executive pay that is sometimes viewed as excessive. Although employee ownership and related forms of shared capitalism appear to be spreading around the globe, further encouragement of the growth of employee ownership would likely deliver an additional societal gain besides those to workers and firms highlighted in recent research (e.g., Kruse, Freeman, & Blasi, 2010).

NOTES 1. Morck et al. (1988) find a nonlinear relationship between the extent of managerial ownership (reflecting managerial entrenchment) and Tobin’s Q. Related issues are also examined by Joskow, Rose, and Shepard (1993). 2. However, there is an extensive literature that examines diverse issues for firms that are majority-owned by nonmanagerial employees. For one example, see Pencavel and Craig (1994); for a review of such studies, none of which examine the determinants of CEO pay, see Bonin, Jones, andPutterman (1993) and Dow (2003). 3. By contrast, majority ownership structures of enterprises in organizations in western economies are relatively homogeneous. Thus, when ownership by nonmanagerial employees occurs, this seldom exceeds 5% of voting equity (Blasi & Kruse, 1991). Although ownership by top managers is more common, instances of managers owning the bulk of shares in a western firm are rare. For example, in a survey of US corporations, Denis, Denis, and Sarin (1997) find that in about 5% of cases (282/5,545 man-years), officers and directors had majority ownership in that firm. 4. The most comprehensive investigation of diverse aspects of a managerial labor market for a transition economy is Eriksson (2005). For general surveys of literature on managerial labor markets in former Soviet economies as well as emerging economies such as China, see Djankov and Murrell (2002) and Estrin et al. (2009). As pointed out in those surveys, our understanding of these aspects of managerial labor markets in those countries is confined to a handful of empirical studies that cover a limited range of countries. 5. One exception is Roomkin and Weisbrod (1999) who examine CEO pay and the comparative behavior of for profit and nonprofit firms. 6. Case study evidence also suggests that the managerial labor market is rather different in state firms than in private firms, with state firms typically having less turnover and relatively more internal promotion (see Mygind & Pedersen, 1996). 7. However, if firms are largely owned by outsiders but firms are part of groups, then institutions connected to the group may play a monitoring role. See Kato and Rockel (1992) for a discussion of the Japanese case. 8. Also, more compressed internal wage differences have been found in actual employee firms, including Mondragon. See, for example, the evidence in Arando, Freundlich, Gago, Jones, and Kato (2011). 9. In these firms, ownership was to be shared equally by all employees (Mygind, 1999). 10. For China, see Kato and Long (2006), for the Czech Republic see Claessens and Djankov (1999) and Eriksson (2005), and for Bulgaria see Jones and Kato (1996). 11. These official Estonian data have tended to be regarded as quite reliable certainly when compared with data for many other transitional countries (see OECD, 2000). 12. It was impossible to gather information on the distribution of ownership within ownership classes. However, theoretical and empirical literature for transition economies has stressed the importance of categories of ownership for enterprise behavior (e.g., Aghion & Blanchard, 1998; Jones, 2004; for the Estonian case, Jones & Mygind, 2002). 13. Comparisons of means for key economic variables in this managerial survey of 220 firms and for the larger ownership survey of 666 do not reveal any statistically
Majority Ownership and Chief Executive Compensation
137
significant differences. Thus, there is no reason to believe that this smaller sample is not representative of the population of Estonian firms that existed during 1993–1997. 14. Although data for Russia are somewhat fragile, in 1997, it appears that in about 15%, managers constituted the dominant group (see Buck, Filatotchev, Wright, & Zhukov, 1999). 15. To be precise, there were only 10 observations of ‘‘no-majority’’ during the whole period – fewer than 1% of the total sample of 1,070. Hence, we restrict our empirical work to those 1,060 observations for firms in which there was a majority owner. 16. The nature and determinants of ownership changes in Estonian firms during a period that partially overlaps with the period examined in this chapter is investigated in greater length by the authors elsewhere (see Jones andMygind, 1999). 17. Typically, the number of observations on economic variables in each ownership category is usually very close to the numbers reported in Table 1 for 1997 – that is, a total of 214 observations, with 11 for firms that were majority stateowned and so on. However, the panel is unbalanced with the number of observations for which data on all variables are available ranging from 909 to 955. There were significantly more cases of missing values for the earlier years with asset data being especially likely to be missing. 18. Such patterns were not unusual during early transition in many economies. See, for example, Fischer, Ratna, and Vegh (1996). 19. However, in part reflecting the small size of the Estonian economy, Estonian firms have always been much smaller than their counterparts in, for example, the former USSR. In turn, presumably this translated into comparatively less overmanning at the start of transition. 20. As such, this ratio of CEO/average worker pay is rather lower than what has been reported for western countries although comparable to what has been observed for some transition economies. Thus, Kato and Rockel (1992) report comparable ratios for Japan of 13 and for the United States of 32. In 1993, the comparable ratio in Bulgaria was 2.9 (Jones & Kato, 1996). 21. To facilitate comparisons of the size of key parameters, our empirical strategy mirrors that used in early studies as reviewed in Murphy (1999). Unfortunately, we are unable to include managerial fixed effects – we do not have information on turnover. 22. Although there are potential econometric pitfalls surrounding issues such as endogeneity and ownership type, unfortunately we do have suitable instruments to begin to address these matters. 23. Executive compensation studies have been mainly undertaken for developed economies and do not measure performance relative to an industry mean, even though such data often are publically available in the west. For transition economies, the use of performance measures relative to industry means was difficult to implement during early transition because such data were not publically available and the relatively few firms in most Estonia industries would have meant that even if such a procedure were feasible it would have been especially sensitive to outliers. 24. Unfortunately, we do not have information on individual CEO attributes such as experience and education and other components of compensation. 25. As indicated earlier, our estimates are for unbalanced panels. If the identical specifications are estimated using a balanced panel for 169 firms, the findings are essentially unaltered from those reported in the text.

26. Alternatively these payments might be a compensating differential – running a state-owned firm might be viewed as either more difficult than a private firm or less prestigious. 27. Nevertheless we report the results contained in Table 3 in view of our interest in the hypotheses concerning pay determination for CEOs in private versus state firms. 28. This is consistent with findings from case studies, as discussed by Mygind (1999). 29. Note also that CEO pay in firms in which managers are majority owners is also about 25% less than comparable pay in foreign-owned firms and only about 13% more than in forms in which employees are majority owners. 30. In part, this follows because performance is related to ownership. Ownership is also potentially endogenous (although our institutional discussion suggests that at least for employee-owned firms, their selection may usually have been arbitrary). In any event, unfortunately, the existing data do not contain any suitable instruments for ownership. 31. The case study evidence suggests that the average size of the board of directors is smaller in Estonian firms (compared to state firms) and that state firms continue to have some directors who are chosen primarily for political reasons.

WORKER ATTITUDES TOWARD EMPLOYEE OWNERSHIP, PROFIT SHARING AND VARIABLE PAY Fidan Ana Kurtulus, Douglas Kruse and Joseph Blasi ABSTRACT Using the NBER Shared Capitalism Database comprised of over 40,000 employee surveys from 14 firms, we investigate worker attitudes toward employee ownership, profit sharing, and variable pay. Specifically, our study uses detailed survey questions on preferences over profit sharing, forms of employee ownership like company stock and stock option ownership, as well as preferences over variable pay in general, to explore how preferences for these different types of outputcontingent pay vary with worker risk aversion, residual control, and views of co-workers and management. Our key results show that, on average, workers want at least a part of their compensation to be performance-related, with stronger preferences for output-contingent pay schemes among workers who have lower levels of risk aversion, greater residual control over the work process, and greater trust of coworkers and management.

INTRODUCTION The prevalence of employee ownership, profit sharing and other performance-based pay schemes has been growing in the past several decades in the United States and other advanced economies. According to the 2006 wave of the General Social Survey, which is a nationally representative survey of individuals conducted by the National Opinion Research Center, over a third of U.S. workers are covered by profit sharing, 18 percent own company stock, and 9 percent own company stock options. Coverage is similar in France, Great Britain, Italy and Japan (Del Boca, Kruse, & Pendelton, 1999; Jones & Kato, 1995). A large part of the previous research on shared capitalist pay schemes in which employees participate in the financial performance of their place of work has focused on the effects of such programs on worker and firm outcomes like productivity, turnover, and profits (Craig & Pencavel, 1992; Kruse, 2002; Kruse & Blasi, 1997; Park, Kruse & Sesil, 2004). But an important aspect that has not yet been explored is worker preferences for different participatory compensation programs, largely due to the dearth of available datasets that are conducive to the analysis of this subject. The current study sheds light on this topic by examining preferences over profit sharing, forms of employee ownership like company stock and stock option ownership, as well as preferences over variable pay in general, and how these preferences depend on worker risk aversion, residual control, and perceptions of co-workers and management. Economic theory predicts that workers will be more favorable toward performance-related pay schemes when they: (i) have low levels of risk aversion, (ii) have greater control over the work process generating payouts (residual control), (iii) trust their co-workers, so that the free rider problem associated with group incentives can be overcome by a cooperative solution, and (iv) trust their managers not to exploit information asymmetries when distributing financial payouts. We investigate the role that each of these factors play in workers’ preferences over employee ownership, profit sharing and variable pay using a unique set of questions asked in the NBER Shared Capitalism Survey of more than 40,000 employees from 14 firms.
Worker Attitudes Toward Employee Ownership
145
This is a novel research area in the employee ownership literature and our findings help to understand how workers respond to different types of participatory compensation schemes. We consider both pay that is tied to overall company performance (profit sharing, company stock and stock option ownership), as well as individual performance-based variable pay (individual bonuses, and commissions), and we will refer to these collectively as financial participation. A strength of our data is that we have individual-level measures of risk aversion, which is often discussed as an important factor in financial participation but is rarely measured. The NBER Shared Capitalism Survey additionally provides unique information on worker residual control and worker perceptions of co-workers and management which are also central to our analysis. We use this detailed information to investigate how preferences for different types of financial participation are shaped by worker risk aversion, residual control, and views of co-workers and management. Our key results show that most workers want at least a part of their compensation to be output-contingent, with stronger preferences for performance-related pay among workers who have lower levels of risk aversion, greater residual control of the work process, and greater trust of co-workers and managers.
THEORY AND PRIOR LITERATURE Our discussion focuses on the following theoretical factors central to perceptions about shared capitalism and variable pay: risk aversion, residual control, and trust in co-workers and management. Worker preferences for employee ownership and other forms of financial participation will reflect the perceived potential costs and benefits of such plans. Risk aversion is viewed as a key factor in most theoretical models of pay-for-performance (Holmstrom, 1979; Shavell, 1979), since the variability of rewards can represent a significant cost for risk-averse workers, and has indeed been found to reduce preferences for output-contingent pay in laboratory experiments (Cadsby, Song, & Tapon, 2007). Moreover, people with lower wealth and base salary will generally be more averse to financial risk since they have less money for discretionary spending and a reduction in income or assets may force them to cut back on necessities. Attitudes toward financial participation will also depend on the perceived potential for higher income, which will depend on worker skills and opportunities for influencing workplace performance. Workers are likely to view group-based rewards more favorably in the presence of practices such as
146
FIDAN ANA KURTULUS ET AL.
employee involvement in decisions (increasing opportunities to influence performance), training (increasing skills that contribute to performance), and job security (providing assurance that one will be able to receive the fruits of higher performance). This can be thought of in the context of the theory of residual returns and residual control, which argues that those who receive residual returns (financial participation) should also receive residual control (power over the work process) in order to provide proper incentives and achieve value-maximizing decisions (Holmstrom & Milgrom, 1994; Jensen & Meckling, 1992; Milgrom & Roberts, 1990; Prendergast, 2002). Several empirical studies have found support for this hypothesis (Ben-Ner, Kong & Lluis, 2010; DeVaro & Kurtulus, 2010; Foss & Laursen, 2005). Moreover, employee involvement in firm decision making may create expectations or desires for sharing in the fruits of those decisions, and workers may become dispirited without some sort of financial reward tied to the consequences of those decisions (Ben-Ner & Jones, 1995; Levine & Tyson, 1990). Preferences for rewards based on company performance are also likely to critically depend on workers’ perceptions about co-workers. The well-known free rider problem in group incentives has been modeled as a prisoners’ dilemma game, in which each participant has an individual incentive to shirk. If the game is repeated in an ongoing relationship, however, several equilibria are possible, including a cooperative equilibrium in which the participants establish a collective agreement to cooperate so that the rewards are higher for all participants (Axelrod, 1984; Fudenberg & Maskin, 1986). Workers in group incentive plans may establish and maintain a commitment to high work standards through cooperation and monitoring, which can generate higher payouts for workers than in a noncooperative setting (Weitzman & Kruse, 1990). This points to co-worker relations as a key ingredient in the effectiveness of employee ownership. Preferences for employee ownership and profit sharing are likely to be low if workers think co-workers are not interested in workplace performance and there is little potential for productive cooperation under group-based rewards, and higher if they think co-workers are interested in workplace performance and can achieve the cooperative equilibrium in the prisoner’s dilemma game by working well together. Finally, preferences for financial participation are likely to be shaped by attitudes toward management. First, workers are unlikely to favor variable pay plans if they do not trust managers to manage well so that there will be rewards to distribute to workers for their hard work. The second issue stems from informational asymmetries inherent in many incentive plans: it can be difficult for workers to determine whether rewards under variable pay systems are being calculated correctly and fairly by management, whereas
Worker Attitudes Toward Employee Ownership
147
this is easier under fixed wage contracts since workers know exact pay levels ex ante. One of the objections of unions to profit sharing, for example, is mistrust that managers will calculate profits in a way that properly rewards workers for their performance (Zalusky, 1986, 1990). If workers do not trust managers to calculate the payouts from financial participation in a competent and honest way, they will be less interested in participating. In sum, based on theory and past research, we expect attitudes toward financial participation to be more positive among workers who are less risk averse, have more residual control, and who trust management and think co-workers are more interested in workplace performance. There has been little published research on the topic of worker attitudes toward financial participation. Kruse and Blasi (1999) summarize 30 public polls conducted between 1975 and 1997 with questions on general perceptions about financial participation systems, finding that a majority of people expressed favorable views of employee ownership and its effects on workplaces; for instance, in one survey 75 percent said they would like to work for an employee-owned and employee-controlled company, as opposed to a company owned by outside investors or government, and in another survey 69 percent thought employee-owners work harder. A number of studies have examined the effect of variable pay on overall job satisfaction among British workers: Green and Heywood (2008) found that performance-related pay in general was associated with increased job satisfaction, Brown and Sessions (2003) showed that workers who participated in performance bonuses, share ownership, and profit sharing were more satisfied with their work environment, and McCausland, Pouliakas, and Theodossiou (2005) found that the influence of performance pay increased satisfaction for the more highly paid but lowered it for the less highly paid. Drago, Estrin and Wooden (1992) found the use of individual and group bonuses to be a positive determinant of job satisfaction in a sample of Australian workers. Cornelissen, Heywood and Jirjahn (2008) showed that among German workers who received performance pay, risk aversion was inversely correlated with overall job satisfaction. Our study contributes to the literature by investigating worker preferences for various forms of financial participation and how these preferences depend on key worker and workplace characteristics.
DATA AND VARIABLES We use the NBER Shared Capitalism Database, which consists of detailed information collected from more than 40,000 employee surveys from 14
148
FIDAN ANA KURTULUS ET AL.
firms, to explore preferences for different forms of employee ownership and variable pay. The NBER data comprise one of the largest worker-level datasets on labor practices and worker sentiment ever collected. The survey was conducted during 2002–2006 using a combination of web-based and paper survey methods, and had a high response rate, averaging 53 percent over the 14 companies. The firms participating in the survey included large multinationals with employment spanning North America, South America, Europe, and Asia, as well as smaller firms with mostly US employees. The sample included eight firms in the manufacturing industry, two hightechnology firms, and four in the service industry. Three of the fourteen companies exceeded 10,000 employees, 5 employed between 1,000 and 10,000 workers, and the remaining 6 employed fewer than 1,000 workers. All of the firms had employee ownership, profit sharing, and variable pay programs, though of varying forms and degrees: 13 had individual bonus plans, 9 had workgroup-based or department-based performance bonus plans, 11 had broad-based profit sharing plans, 5 had broad-based stock option plans, 8 had standard employee stock ownership plans (ESOPs), 1 had a 401(k) employee stock ownership program, 4 had employee stock purchase plans, and 3 had 401(k)’s with company stock. Most had combinations of these plans. To investigate the role that risk aversion, residual control, and perceptions of co-workers and management play in workers’ preferences for financial participation, we make use of a unique set of questions asked in the NBER Shared Capitalism Survey capturing these concepts. We now turn to a discussion of the key variables used in our empirical analyses.
Dependent Variables We examine four variables reflecting worker preferences for financial participation as dependent variables in our regression analyses. The first one captures worker preferences for variable pay broadly and is based on a question asked in the NBER Shared Capitalism Survey indicating the percentage of pay the respondent would like to receive as variable compensation (which includes all forms of output-contingent pay that is based on individual, group, and company performance). Next we examine worker preferences for various forms of employee ownership based on questions indicating the respondent’s preference for being paid at least in part based on company performance (profit sharing, company stock, or stock options), preference for the extent to which the respondent’s next pay increase

149
depends on company performance, and preference for getting a portion of compensation in the form of company stock and stock options. These four dependent variables are defined formally below. Worker Preferences for Financial Participation: Preference for variable pay
Proportion of pay the worker would like to receive as variable compensation (13 firms surveyed)
Preference for company-based incentives
Dummy variable equaling 1 if the worker prefers that he or she be paid in part with a variable amount dependent on company performance, through profit sharing, company stock, or stock options; 0 if all fixed wage or salary, with no profit sharing, company stock, or stock options (13 firms surveyed)
Preference for company-based incentives in next pay increase
Worker’s preference that his or her next pay increase come in the form of 1 ¼ All fixed wages, with no profit sharing, company stock, or stock options; 2 ¼ Split between fixed wages and profit sharing, company stock, or stock options; 3 ¼ All in the form of profit sharing, company stock, or stock options (5 firms surveyed)
Preference for stock over cash incentives
Worker’s preference for getting some of his or her compensation from company stock and stock options as opposed to a cash incentive plan on a 1 (cash incentive plan) to 5 (company stock and stock options) scale (3 firms surveyed)
Key Independent Variables The key independent variables in our analysis are those that capture worker risk aversion, residual control, and perceptions of co-workers and management.

One of the unique features of the NBER Survey is the presence of information on individual-level risk aversion, which plays a central role in theoretical models of the employee–employer relationship, but is rarely available in existing datasets. Our primary measure of the extent to which the worker is averse to risk is based on the NBER Survey question ‘‘Some people like to take risks and others dislike taking risks. Where would you place yourself on a scale of how much you like or dislike taking risks, where 0 is hating to take any kind of risk and 10 is loving to take risks?’’, from which we define variable Risk Averse such that values greater than or equal to 7 on this scale correspond to ‘‘low risk aversion,’’ greater than 3 and less than 7 is ‘‘medium risk aversion’’, and less than or equal to 3 is ‘‘high risk aversion.’’ As discussed earlier, people with lower wealth and base salary will generally be more averse to financial risk since pay variability that results in pay reduction is more likely to force them to cut back on necessities, so we also examine the worker’s annual base salary and family wealth under the framework of risk aversion.
Risk Aversion Variables: Risk averse
Worker’s self-assessment of his or her risk preference, where 1 ¼ low risk aversion; 2 ¼ medium risk aversion; 3 ¼ high risk aversion
Base pay
Worker’s annual base pay the previous year excluding overtime, bonuses, and commissions (in thousands)
Wealth
Assets of the worker and the worker’s spouse including the value of their house minus the mortgage, their vehicles, stocks and mutual funds, cash, checking accounts, retirement accounts including 401(k), and pension assets (in thousands)
The second key element that is likely to shape attitudes toward financial participation is residual control, or the ability to influence one’s potential for higher income, which will depend on worker skills and opportunities to influence workplace performance through employee involvement in decision making, training, and assurance that the worker can reap the rewards of higher performance through job security. These
Worker Attitudes Toward Employee Ownership
151
variables, which we group under the heading residual control, are defined below. Residual Control Variables: Decision making
Dummy variable equaling 1 if the worker is involved in organized workplace decision making through teams, committees, or task forces that address workplace issues such as product quality, cost cutting, productivity, health, and safety; 0 otherwise
Training
Dummy variable equaling 1 if the worker received any formal training from the employer in the last 12 months, such as in classes or seminars sponsored by the employer; 0 otherwise
Job security Dummy variable equaling 1 if the worker’s response to the question ‘‘Thinking about the next 12 months, how likely do you think it is that you will lose your job or be laid off?’’ is ‘‘not at all likely’’ or ‘‘not too likely’’; 0 if the worker’s response is ‘‘very likely,’’ or ‘‘fairly likely’’.
As discussed earlier, preferences for company performance-based rewards in particular are likely to depend on workers’ perceptions about whether their co-workers are committed to workplace performance and whether they trust management to distribute payouts from workplace rewards correctly. We therefore include the below two independent variables. Perceptions of Co-Workers and Management: Co-worker interest Worker’s perception of his or her co-workers’ interest and involvement and involvement in company-wide issues on a 1–7 scale, with 1 indicating little interest and involvement and 7 indicating great interest and involvement Management Worker’s perception of the trustworthiness of his or trustworthiness her company in keeping its promises on a 0–4 scale, with 0 indicating not trustworthy and 4 indicating highly trustworthy

Control Variables Beyond the variables that are central to our analysis, all of our regression models include a rich array of worker and workplace characteristics as control variables. These are worker demographic variables including gender, age, and education level; and job characteristics variables including occupation, managerial level, firm tenure, whether the worker is closely supervised, and whether pay is at or above market level. We also control for the ease with which workers can observe their coworkers’ effort, since this is likely to influence the extent to which perceptions about how involved co-workers are in company issues (Coworker interest and involvement), one of the main independent variables we consider, affects preferences for shared capitalism. Fuller definitions and descriptive statistics of these control variables are provided in the appendix.
METHODOLOGY As a first step in our empirical analysis, we will examine unconditional means of our main dependent variables to explore preferences over financial participation broadly across all workers in our sample. Second, we will examine how preferences for financial participation vary with worker risk aversion, residual control, and perceptions of co-workers and management by estimating cross-sectional regressions of attitudes on these main independent variables, controlling for the array of worker and workplace characteristics described earlier. We will estimate least squares, probit, and multinomial probit models, depending on whether the dependent variable is a continuous, dummy, or multivalued variable, respectively. It is important to note that these cross-sectional regression models do not capture causal relationships, but rather conditional correlations among the variables of interest. For example, it is possible that workers with a greater preference for financial participation sort themselves into firms with greater use of financial participation, greater residual control for workers, and workplace climates with high levels of trust. We investigated this possibility by also estimating regressions that included firm-fixed effects, with very similar results for the variables of interest; here we report the results without firm effects to take advantage of both within- and

153
between-firm variation. It also remains possible that within a firm, workers will be sorted into jobs based on personal characteristics correlated with preferences over financial participation. It may be, for example, that being in a decision-making team does not create greater interest in financial participation, but workers with greater interest in financial participation select themselves into positions that are part of decision-making teams. Even in the latter case, finding a positive relationship strongly suggests an important linkage between residual control and residual returns for workers. So while we cannot definitively determine causality (as with most nonexperimental data), our results will nonetheless shed important light on how preferences for financial participation are related to worker risk aversion, residual control and workplace climate, and the conditions under which variable pay plans are viewed positively by workers and are most likely to be effective.
UNCONDITIONAL STATISTICS Summary statistics for the main variables used in our empirical analyses are shown in Table 1, along with distribution charts for selected variables. Most workers desire between 0 and 30 percent of their compensation to be comprised of variable pay, though there is considerable variation in this preference across workers as illustrated in Fig. 1, with an average of 20 percent (Preference for variable pay). When asked whether workers prefer to be paid at least in part with variable pay that depends on company performance through profit sharing, company stock or stock options, as opposed in getting all fixed salary, a vast majority of respondents, 78 percent, say they prefer to have some company performance-dependent variable pay (Preference for company-based incentives). Only 27 percent of workers would like their next pay increase to come in the form of all fixed wages with no profit sharing, company stock or stock options, whereas 60 percent would like a combination of the two types, and 13 percent would like their next raise to consist entirely of profit sharing, company stock or stock options (Preference for company-based incentives in next pay increase). Workers’ preferences in favor of company-performance-based pay is also evident in the distribution of the variable Preference for stock over cash incentives, where most workers picked categories 3 and 4 on a scale of 1–5 indicating their preference for getting some of their compensation from stock and stock options as opposed to a cash incentive plan.

WHICH WORKERS PREFER FINANCIAL PARTICIPATION? The earlier discussion showed that most workers want at least a part of their compensation to be output-contingent, and prefer to be paid at least in part based on company performance. But it may well be that there is variation across these attitudes by the worker’s degree of risk aversion, residual control, and perceptions of co-workers and management. We now explore what types of workers prefer variable pay, and what kinds of variable pay they prefer, by estimating regressions of our various preference measures on the main independent variables of interest, and controls. Table 2 illustrates least squares regression results for Preference for variable pay, indicating the proportion of total pay the worker would like to receive as

variable compensation, and provides strong support for our hypothesis on the relationship between risk aversion and preferences for variable pay: the proportion of compensation workers would like to receive as variable pay is negatively related with their degree of risk aversion – an increase in risk aversion from the ‘‘low’’ category to the ‘‘high’’ category is associated with a decrease in the desired proportion of pay comprised of variable compensation of over 8 percentage points, on average. Also, the proportion of compensation workers would like to receive as variable pay is statistically significantly positively related with family wealth and base salary which can insulate

workers against fluctuations in compensation created by variable pay. Second, there is some support for the hypothesis that workers have greater preference for residual rewards when they also have residual control – the proportion of pay the worker desires in his or her compensation is significantly positively related with employee involvement in workplace decision making, and is also positively related with formal job training and job security though these last two estimates are not statistically significant at conventional levels. Third, in support of our hypothesis on perceptions of co-workers and management, preference for variable pay is positively related with co-worker interest and involvement in company-wide issues and trust in management, and both of these relationships are statistically significant at the one-percent level, indicating that workers are more interested in shared capitalism when they can trust others in the workplace.1,2 Table 3 illustrates the probit marginal effects for Prob (Preference for company-based incentives ¼ 1), the probability that the worker prefers that he or she be paid in part with variable pay based on company performance (such as profit sharing, company stock, and stock options) over being paid fully in the form of fixed salary. We find even stronger evidence in favor of our hypotheses here than in the previous table: preference for companyperformance-contingent pay is negatively associated with risk aversion, positively associated with family wealth and base salary, positively associated with all three measures of residual control, and positively associated with confidence in co-workers and management, as predicted. We next turn to workers’ preferences over the portion of pay increases comprised of company-performance-based variable pay by focusing on the three-valued Preference for company-based incentives in next pay increase, which equals 1 if the worker prefers that his or her next pay increase is comprised of all fixed wages, with no profit sharing, company stock, or stock options; 2 if it is split between fixed wages and profit sharing, company stock, or stock options; and 3 if it is all in the form of profit sharing, company stock, or stock options. Table 4 illustrates marginal effects from a multinomial probit regression of Preference for company-based incentives in next pay increase on our risk aversion, residual control, and co-worker and management perceptions variables, and worker controls, with the three columns corresponding to the probability that a worker chooses values 1, 2, or 3, respectively. We find that workers who are more risk averse are less likely to want their next pay increase to be partly or completely comprised of company-performance-based pay, and more likely to prefer that it is entirely comprised of fixed wages, corroborating our hypothesized relationship between risk aversion and attitudes toward financial participation.

and Preference for company-based incentives in next pay increase is not statistically significant. Finally, though trust in management is associated with wanting a portion of one’s pay raise to be contingent on company performance, co-worker interest and involvement in company-wide issues does not have a statistically significant relation with Preference for companybased incentives in next pay increase. Table 5 shows results from a least squares regression of preference for receiving some compensation from company stock and stock options as

opposed to a cash incentive plan on a 1 to 5 scale (Preference for stock over cash incentives). We can interpret this as capturing whether the respondent prefers having stock or cash in his or her pocket. The worker’s selfassessment of his or her own risk aversion is strongly negatively correlated with preference for stock-based compensation as opposed to cash incentives, as expected. However, family wealth and base salary have a statistically significant positive, albeit small, correlation with preference for stock-based compensation over cash incentives. All of our residual control variables and management and co-worker trust variables are positively related to Preference for stock over cash incentives, in support of our hypotheses.3
CONCLUSION This study uses the NBER Shared Capitalism Survey to examine a relatively unexplored topic in the research on participatory pay schemes, namely worker preferences for employee ownership, profit sharing and variable pay, and how these preferences depend on three key worker and workplace characteristics: worker risk aversion, residual control, and perceptions of coworkers and management. We find that, on average, workers desire around 20 percent of their compensation to be comprised of variable pay. Most workers prefer to be paid at least in part based on company performance, through profit sharing, company stock, or stock options, and in particular they prefer getting stock and stock options as opposed to cash incentives. Furthermore, our regression results clearly indicate that risk aversion is a major factor reducing preferences for variable pay plans. This is supported not only by the strong coefficient estimates on the risk aversion variable, but also by the coefficient estimates on two key employee characteristics that are expected to be related to risk preferences, namely base pay and family wealth. An important finding, though, is that workplace policies help to improve worker perceptions of variable pay. The finding that workers are more likely to prefer performance-based pay if they have decision-making power, formal job training, and job security at their workplace supports the theory that residual control and residual returns are complementary. Future research would be valuable on the form of this relationship (e.g., linear or nonlinear, including whether there are threshold effects), and whether complementary residual control practices can help make shared capitalism more appealing to groups who are more risk-averse.

Workplace culture also is a key variable. Workers are unlikely to favor variable pay plans if they do not trust managers (either to manage well so that there will be rewards, or to calculate rewards accurately and honestly). Their attitudes are also influenced by how they perceive their co-workers: if they have little reason to expect their co-workers to perform well under a performance-based pay plan, they will not be optimistic about the prospect for rewards. The findings on workplace policies and trust of co-worker and managers indicate that preferences over variable pay plans are not determined by any fixed mindset or personal characteristic of workers, but appear to depend on the context in which the plans are implemented. This is consistent with research on the performance effects of employee ownership and profit sharing, which shows that while these plans are associated with higher performance effects on average, there is substantial dispersion in estimated effects across and within samples (Doucouliagos, 1995; Freeman, 2007; Kaarsemaker, 2006). This dispersion is likely to be explained in part by employees’ neutral or negative reactions in workplaces that do not provide supportive environments, in contrast to positive reactions with increased employee effort and cooperation when the environment is supportive. Research has begun to identify how specific workplace policies condition the effects of group incentive plans (Kruse, Blasi, & Park, 2010). Further research that delves into the role of workplace policies and cultures in financial participation would be valuable in determining how and when these plans can affect performance and worker welfare, and the likelihood that they may expand in the 21st century.
NOTES 1. Apart from these main results on how preferences for variable pay depend on risk aversion, residual control and perceptions of co-workers and management, we also uncovered some interesting findings on the relationships between the control variables and Preference for variable pay. For example, women have a lower preference for variable pay, which aligns with evidence from past studies using laboratory and field experiments that women tend to be more risk averse than men (Dohmen & Falk 2011; Dohmen et al., 2011; Niederle & Vesterlund, 2007). We also find that workers in sales and customer service occupations have the strongest preference in favor of variable pay, a possible explanation for which is that output is more readily linkable to individual performance than for workers in many other occupations (e.g., number of units sold or number of customers assisted), and this reduces problems of free-riding so that such workers may view output-contingent compensation as a more fruitful reward for their effort. Among other interesting

results is that workers with longer tenure at the firm prefer a lower share of variable pay, supporting the idea that workers who are closer to retirement are often loathe to introduce risk into their compensation as they have less time remaining in the labor market to recoup potential losses. To streamline and focus our discussion around the key variables of interest (risk aversion, residual control, and perceptions of coworkers and management) we do not present these results here, but they are available from the authors. 2. Since Preference for variable pay has a lower bound of zero we also estimated an analogous regression using a tobit model and obtained very similar results. 3. As a robustness check we also estimated all of our regressions with firm-fixed effects, and the results were very similar to the baseline results we report here, both in magnitude and significance. These additional results are available from the authors.

PERFORMANCE-RELATED PAY, UNIONS, AND PRODUCTIVITY IN ITALY: EVIDENCE FROM QUANTILE REGRESSIONS Mirella Damiani and Andrea Ricci ABSTRACT This chapter explores the relationship between performance-related pay (PRP) and productivity in the Italian economy. It contributes to the literature in two main ways. First, it provides estimates for the PRP – productivity relationship based on a nationally representative sample of manufacturing and services companies (other studies on Italy are more limited in scope, since they focus on specific sectors). Second, it addresses the question of firms’ heterogeneity, an aspect so far not examined in relation to PRP in Italy. We use a two-step approach. In the first step, we estimate a classical production function using longitudinal data on the balance sheet variables of Italian firms over the period 2002–2005. In the second step, we regress the distribution of the firm-specific fixed effects on dummy variables for the presence of PRP and unions, as well as on control variables for the year 2005. The most important results are that the adoption of PRP is positively and uniformly correlated with productivity throughout the whole distribution and that the presence of trade unions has a positive association with firms’ unobserved productivity across all

INTRODUCTION This chapter explores the relationship between performance-related pay (PRP) and productivity in the Italian economy, using a unique dataset that collects information at firm level for both manufacturing and services sectors. It contributes to the literature in two main ways. First, it provides estimates for the PRP – productivity relationship based on a nationally representative sample of manufacturing and services companies. Until now, all available research has been restricted to large companies, selected sectors or particular areas in the north of the country (see Origo, 2009 for a summary), while no studies have considered this issue on a national scale. Second, it addresses the question of firms’ heterogeneity, so far not examined in relation to PRP in Italy and considered in only a limited number of other European countries. In fact, only a few empirical studies on wage rules, productivity and heterogeneity in Europe have been carried out (e.g., Bastos, Monteiro, & Straume, 2009, for Portugal; Wagner, Addison, Claus Schnabel, & Schank, 2004, for Germany). We adopt a two-step estimation procedure, similar to that used by Black and Lynch (2001), together with quantile regressions. In the first step, we estimate a classical production function using longitudinal data on the balance sheet variables of Italian firms over the period 2002–2005. The distribution of average firm residuals (obtained by the first step) is then used as a measure of the firm fixed effect and regressed, in the second step, using quantile methods on our 2005 data for PRP, unionization and other firm and workplace characteristics. Two main results emerge: first, the adoption of PRP is positively and uniformly associated with productivity throughout the whole distribution; second, the presence of unions has a positive association with firms’ unobserved productivity across all quantiles, being significantly higher for the best performing firms (those placed at the highest quantile of the productivity distribution).

Italy is an interesting case study, since a process of large-scale reform of its industrial relations system began in the early 1990s. However, since the mid-1990s, Italian labor productivity growth has recorded a significant slowdown. Also, as reported by Daveri and Jona-Lasinio (2005), growth accounting has revealed the crucial influence of total factor productivity (TFP), the component of productivity that depends not on capital deepening but on organizational strategies. Over the same period, similar labor market reforms have been introduced in many other European countries, with the aim of favoring ‘‘flexibility’’ in industrial relations and linking wage increases to the dynamics of labor productivity. This type of reform raises many issues (OECD, 2004, Chapter 3). One concern is related to the expected positive effects of wage flexibility and PRP on productivity, as well as to the possible negative side-effects caused by rent-sharing, facilitated by agreements at firm level. This theme has stimulated new interest in recent empirical literature. In two European economies, Germany (Gu¨rtzgen, 2009) and Belgium (Rusinek & Rycx, 2008), it has been ascertained that the disadvantages of distributive, rentsharing rules outweigh the positive effects of flexible wage structures. Another critical issue regards the strategic role of complementary workplace practices which may influence the effects of PRP. For instance, Black and Lynch (2001) find that unionized plants in the American economy, where joint decision making accompanies incentive payments, record higher productivity performance than non-unionized plants. The adoption of ‘high involvement’ systems would thus seem to be a necessary condition for making contingent pay settings effective on productivity growth, as shown by a growing body of empirical literature (see for a survey Godard & Delaney, 2000). Micro-evidence reveals that disparities in efficiency gains may persist even among firms within a single country. Indeed, it is now widely recognized (after the contribution on international trade by Melitz, 2003) that firms are heterogeneous with respect to key variables, including productivity and wage setting systems. The controversial influence of PRP thus seems to find its natural place within the literature on heterogeneity. The present study integrates these elements – the role of PRP and firms’ heterogeneity – and tries to fill this gap. This paper is organized as follows. The second section briefly discusses the theoretical and empirical literature. The third section presents the Italian data that has been used and offers descriptive statistics. The fourth section illustrates the econometric framework. The fifth section presents the estimation results, and the sixth section concludes.

PRODUCTIVITY, PERFORMANCE PAYMENTS, AND UNIONS: A SHORT REAPPRAISAL Our research is related to various fields of theoretical and empirical literature. One is that of profit-sharing, more recently known as ‘‘employee financial participation,’’ which posits that payments of collective bonuses, such as profit-sharing, constitute a commitment device to motivate groups of workers and their collaborative relationships.1 Profit sharing is held to generate beneficial effects in the form of higher effort and work quality, higher commitment and incentives to firm-specific human capital, better teamwork, greater workforce cooperation in facing new technology and organizational changes, lower labor turnover, and longer average tenure (see, among others, the contributions of Estrin, Grout & Wadhwani, 1987; Jones & Pliskin, 1991; Svejnar, 1982). It is argued that these collective incentive schemes are more likely to be offered when total output is the result of the efforts of many agents and individual contributions cannot easily be identified (Fitzroy & Kraft, 1992; Holmstrom, 1979). In such cases, the absence of group incentives may lead to inferior Nash equilibria, associated with low levels of productivity due to limited cooperation. Conversely, offering collective incentives in the form of contractual shares of companies motivates workers to high levels of cooperation and allows lower monitoring costs (Fitzroy & Kraft, 1987). Collective bonuses are nevertheless not exempt from potential drawbacks. The very fact that they are collective may induce employees to free-ride on the efforts of others and thus cut productivity. Horizontal mutual monitoring and peer pressure among workers may be a solution to this problem (Kandel & Lazear, 1992). Freeman, Kruse, and Blasi (2010) have recently put forward evidence that employees believe they are able to monitor the activities of their fellows, a precondition of peer pressure. Moreover, employees in firms with ‘shared capitalism’ (i.e., those with profitsharing and/or employee share ownership) respond more readily to the shirking of their colleagues Similar empirical confirmation is given by Mas and Moretti (2009), who find that workers whose efforts may be noticed by their fellows display more cooperative attitudes. Negative externalities (which are pervasive in workplaces), are thus internalized not because of altruistic behavior, but because peer pressure discourages free-riding, especially when workers expect that many future interactions with the same peers will occur. More generally, a plausible solution to the quelling of free-riding attitudes is the promotion of team culture and employee participation in decision

making, a policy that contributes, like financial participation, to increasing commitment (Blinder, 1990; Jones & Pliskin, 1991;2 Kruse, Freeman, & Blasi, 2010). On empirical grounds, a growing body of research suggests that the PRP– productivity relationship may be positive, as shown by the first report of the experience in European countries (Uvalic, 1991), as well as other studies for major industrialized economies (see, among others, Kruse, 1993; Pe´rotin & Robinson, 2003). Experiences in more than 20 countries offer empirical evidence of the positive or, at least, neutral effects on productivity, and the discrepancies may be attributed ‘‘to differences in participatory practices in firms with profit-sharing plans’’ (Pe´rotin & Robinson, 2003, p. 22).3 Another field of literature surmises that individual bonuses linked to performance may be an efficacious device to motivate single employees. These studies, appraised by Prendergast (1999), point out that the ‘‘power of incentives’’ depends above all on motivation and sorting. Pay settings that change from rewards based on input measures to payments related to output outcomes may induce dramatic improvements, half of which are explained by the attraction of workers of higher ability (Lazear, 2000). The same field of literature has paid close attention to interactions with other packages of good workplace practices, giving rise to many studies exploring the ‘‘value of the complementary role of human resource practices’’ on nationally representative samples of enterprises (Black & Lynch, 2001) or insider econometric case studies within firms (Ichniowski & Shaw, 2003). Controversial aspects of incentives are highlighted by Bandiera, Barankay, and Rasul (2005), who show that employees underperform when wages are linked to relative performance, since workers whose efforts impose negative externalities on their fellows internalize fear retaliation. The consequence is that the average worker’s productivity is significantly lower under relative incentives than under piece rates. In another study, Bandiera, Barankay, and Rasul (2010) examine the importance of social ties across workers and find positive spillover effects where social ties exist, as a given worker’s productivity is significantly higher when that person works together with friends, especially those who are more able. To motivate workers, firms may therefore choose to exploit social incentives as an alternative to monetary incentives. Another controversial aspect arises from the possible trade-off between extrinsic and intrinsic motivations, since contingent rewards may conflict with intrinsic motivation, so impairing performance (Benabou & Tirole, 2003).

A third body of literature considers a problematic line of inquiry, namely the collective actions of workers and their representatives. It has been argued that, in conditions of imperfect competition and high levels of unionization, company wage agreements cause the redistribution of rents, as well as collusive behavior between management and employees. Empirical evidence is offered by Hu¨bler and Jirjahn (2003), who find that, in German firms, in the case of company negotiations with unions, rent-sharing effects are more pronounced. Another view emphasizes the positive influence of unions, whose presence tends to generate improvements in productivity, decreases in the dispersion of earnings and reserves greater space for the workers’ voice (see the ample discussion in Addison & Hirsch, 1989). Nevertheless, the effects of unions on pay settings and productivity are ambiguous, and it is not surprising that international evidence shows contradictory findings. For instance, in the United States, Black and Lynch (2001) estimate that unionized establishments that adopt incentive-based compensations (associated with joint decision making) have higher productivity than other similar non-union plants. In our case study, Italy, Origo (2009) reports opposite results for the metal-working sector. She estimates the effects of a shift in a firm’s pay strategy from a fixed to a flexible wage, based on panel data, for a representative sample of Italian metal-working firms in the 1990s. She finds that, in line with theoretical predictions, the ‘‘treated’’ firms, that is, firms adopting PRP, have positive effects on labor productivity growth (of around 7–11%), with beneficial effects shared with employees in the form of higher wages (around 2–3%). However, her estimates suggest that productivity effects are greater in low-unionized firms, whereas the opposite is true for remuneration, thus showing that high-unionized companies are more oriented toward rent-sharing. The dataset used in this chapter, which gives information on the workplace practices in a single year (2005), does not enable us to identify causal effects, like those obtained with the Propensity Score Matching estimator used by Origo. However, our unique dataset contains more recent information and a nationwide sample of firms, representative of the whole Italian economy, unlike Origo’s data, which refers to the 1990s and to one sector only. The data we use cover all non-agricultural sectors and companies of all sizes, as well as containing a wealth of information on firm and employee characteristics (see the third section). The same data were used in a previous study (Damiani & Ricci, 2009) aimed at identifying the main factors leading to the adoption of PRP. The study found marked differences across sectors and regions and a greater

presence of unions in PRP firms, as opposed to non-PRP firms. This paper integrates our 2009 analysis, addressing the efficiency issue and estimating the extent to which the PRP–productivity link is affected by firm timeinvariant heterogeneities.
DATA AND DESCRIPTIVE STATISTICS Our empirical study is based on a nationally representative sample of manufacturing and non-manufacturing firms, obtained by merging information from two different sources: balance-sheet data from the Bureau Van Dijk AIDA archive and firm-level information on PRP and other workplace practices from the ISFOL Employer and Employee Survey (RIL). The ISFOL-RIL survey is a firm survey that collected cross-sectional information relative to 2005 about personnel organization, recruitment strategies, position of employees, training investments, presence of unions, adoption of PRP schemes and other workplace characteristics. It refers to firms operating in the non-agricultural private sector and includes both partnership and limited companies, for a total sample of 21,728 firms. As far as PRP is concerned, each firm is asked whether or not such a scheme is adopted. Unfortunately, we do not know whether the different types of schemes are based on firm-, group-, or individual-performance. Besides, the dataset does not provide statistics on how many workers in the firm receive PRP or whether these schemes are offered to all or to a selected group of employees (managers, blue-collars, or all workers). Therefore, our PRP-variable is a dummy variable simply indicating the existence or not of a PRP scheme of some kind. As regards unions, the respondent firm is asked whether there is a form of employee representation of any kind in the firm. We thus have a second dummy variable indicating the presence of unions at firm level. Furthermore, we have information about the workplace characteristics and business strategies of each firm (detailed definitions of all variables are given in the Table A1). The AIDA database contains the annual accounts for limited companies that had turnovers of over 100,000 Euros in 2004 (the turnover threshold was previously 500,000 Euros). This database is a source of information on value added, capital, labor, and R&D for the period between 1997 and 2005 (see the Appendix). To link information concerning workers’ characteristics to indicators of firm performance and accounting variables, a sub-sample of the RIL dataset
176
MIRELLA DAMIANI AND ANDREA RICCI
was merged, as said above, with balance-sheet information from the AIDA archive for a period of four years (2002–2005), using company tax codes. Thus, the merged RIL-AIDA sample contains cross-sectional information about employees’ participation and other workplace practices for 2005, and the longitudinal accounting data for the period 2002–2005. Given the characteristics of the RIL-AIDA dataset, the merged sample is representative only in the case of limited companies. Also, we exclude firms with fewer than five employees, applying a filter to retain only those characterized by a minimum level of organizational structure. After matching and data validation, we obtained an unbalanced panel of 6,160 firms. Descriptive Statistics In this section, we present descriptive statistics of the AIDA-RIL merged sample for the year 2005. In view of our focus on heterogeneity, we single out three groups of firms, according to their average productivity performance over the period 2002–2005: ‘‘low performers’’ fall in the group between the 1st and 25th percentiles of the productivity distribution, ‘‘middle performers’’ in the group of firms whose productivity is between the 50th and 75th percentiles of the average distribution, and ‘‘high performers’’ are those firms with productivity higher than the 75th percentile. We then examine the main characteristics of these different groups of firms and of the whole sample. As regards enterprise characteristics, we examine the value added, fixed capital, a dummy variable indicating whether the firms compete in the international market. We group firms in four classes (5–9, 10–49, 50–249, and more than 250 employees), four geographical macro-areas (the NorthWest, North-East, Central, and Southern regions of Italy) and eight 2-digit sectors.4 In the case of workers characteristics, we consider the percentage of women, the professional composition of employees (managers and supervisors, white- and blue-collar workers), the proportion of fixed-term contracts and trained workers. For workplace characteristics we include two dummy variables indicating the adoption of PRP and the presence of unions at firm level, respectively. We also take into account the local unemployment rate and the vacancy rate for each firm, principally to control labor market tightness. Table 1 reports the summary statistics for these variables. First, we consider a group of variables related to three firm strategies: capital accumulation, internationalization, and incentive wage settings. The

typical profile of high-performer firms emerges clearly from our data: they are more active in terms of capital accumulation, more frequently represented in international markets (as recent literature on internalization has shown, Mayer & Ottaviano, 2007), and more oriented toward adopting incentive pay systems. The opposite is true for low performers, while companies in the intermediate group occupy an intermediate position in terms of capital accumulation, exposure to international competition, and adoption of PRP. Second, we find that differences between firms, ranked by productivity, are related to workforce characteristics. As expected, over-achiever firms have more trained employees and make less use of fixed-term contracts; they also have lower percentages of women on the staff. Third, we ascertain the unambiguous role of industrial relations: overperformers show high levels of unionization and operate in conditions of higher labor market tightness, but also have fewer recruitment problems in filling vacant jobs. Lastly, we observe that the ranking order of companies is probably influenced by other features, such as specific internal conditions (size and sector) and external factors (geographical location). One clear result is that the greatest incidence of high performers is to be found among large-sized firms. This result is consistent with that obtained by Pagano and Schivardi (2003), who show that size (because of its influence on innovation activity) impacts on growth and plays a role in cross-country comparisons for European countries, including Italy. In addition, Table 1 shows diverging patterns between industrial and services sectors: the majority of under-achiever firms are in trade, hotels and restaurants, whereas the best performers are in manufacturing, confirming the hypothesis that sector specialization contributes to explaining disparities between successful and unsuccessful Italian firms. Table 1 also shows regional gaps: the highest productivity gains are recorded in North-West Italy, whereas North-Eastern regions do not show clear characterization in terms of company success. Other summary statistics that distinguish firm with and without PRP are reported in Table 2. Some fundamental differences emerge between firms adopting PRP and others. The former are generally much larger firms, and, over the period 2002–2005, achieved higher average value added and higher capital per worker, and were more present in international markets. In terms of industrial relations, we observe a more diffuse presence of unions in PRP firms, suggesting the existence in those firms of more intensive collective actions by employees.

As regards the workforce, the main differences are the higher proportions of men and trained employees, as beneficiaries of PRP, and a lower percentage of fixed-term contracts. The Econometric Framework The econometric strategy used to analyze the relation between PRP and firm productivity is based on a two-step estimation procedure and quantile regression methods. The two-step estimation procedure is similar to that used by Black and Lynch (2001) and allows us to exploit the specific structure of the AIDA-RIL merged sample, where each firm presents longitudinal information on balance-sheet variables for the period 2002–2005 and cross-sectional information on PRP adoption and other workplace characteristics for 2005. In the first step, panel data methods are used to estimate the parameters of the timevariant input factors (i.e., capital and labor) of a classical Cobb–Douglas production function. OLS and quantile regression methods are used in the second step to estimate the coefficients associated to PRP and other workplace characteristics (obtained from the 2005 RIL survey) over the whole distribution of the firm-specific fixed effects estimated in the first step. The coefficients of the production function can be estimated consistently with the fixed-effect estimator. However, the within-estimator tends to go too far in discarding potentially valuable cross-sectional information, because the impact of observed (almost) time-invariant factors, such as sector, PRP, and other quasi-fixed variables in the production function cannot be identified, or measurement errors may explain a large part of their variance (Dearden, Reed & Van Reenen, 2000; Ichniowski, Shaw, & Prennushi, 1997; Griliches & Mairasse, 1995). This feature proves to be a crucial hindrance in our case, because we know only whether or not an establishment adopts PRP in 2005, and this institutional variable does not change much over time. As PRP is treated as a quasi-fixed variable, we assume that firms which adopted PRP in 2005 also adopted a PRP scheme before and after that year. On the contrary, the use of the (within) fixed effect method could act as the lower-bound estimate of the correlation between PRP and firm productivity, taking into account firm unobserved heterogeneity. As shown by the related econometric literature on productivity, recently surveyed by Van Biesebroeck, 2007, estimations of a Cobb–Douglas production function by OLS produces overestimates, due to the correlation between inputs and productivity. Conversely, the fixed effects model gives underestimates, because of limited within group variation (especially in short panels) and
Performance-Related Pay, Unions, and Productivity in Italy
181
amplifies measurement errors. In between these two methods are all the others. In our case, since our main aim is to estimate the correlation between PRP and firm productivity, taking into account firm unobserved heterogeneity, we choose to estimate the Eq. (1) using only the within fixed effect method. On the contrary, the use of the GMM method to address potential endogeneity of input variables of the Eq. (1) is not feasible in our case, given the unavailability of longitudinal data for a longer span of time. Note also that the GMM estimator does not allow us to solve the endogeneity problem of the adoption of PRP in 2005. As regards the second step, the quantile regression method offers notable advantages over the least-squares method when the coefficient of PRP varies significantly across the distribution of firm productivity. Such variations occur when, for example, firm unobserved heterogeneities in terms of management quality and norms of industrial relations map the observed distribution of firm productivity. Furthermore, quantile estimates are robust relative to least squares estimates when there is significant heterogeneity, because they assign less weight to outliers and are robust to departures from normality. We follow the two-step procedure, as described below. In the first step, we estimate a classical Cobb–Douglas production function with two input factors, capital and labor. The following specification is thus used: ln Y it ¼ a ln K it þ b ln Lit þ T t þ ai þ it
for i ¼ 1; . . . ; 6160; t ¼ 2002; . . . ; 2005
(1) where Yit is the value added of firm i at time t, Kit the physical capital, Lit the number of employees, Tt the year dummies, to control for the business cycle, ai the unobserved firm-specific fixed effect, and eit the idiosyncratic error term. Then Eq. (1) is estimated with a within-estimator. On the basis of these first-step estimates, for each firm we calculate the average estimated fixed effect ai over the period 2002–2005, to obtain an estimate of the establishment-specific fixed component. The distribution of this component is then regressed over the establishment variables, which are quasi time-invariant, and over the employment characteristics. The second-step estimation is performed with quantile regressions over the following equation: a^i ¼ dy PRPi þ ay U i þ Zy X i þ ui
(2)
where i ¼ 1; . . . ; N is the number of observations in 2005, y the y-quantile being analyzed, a^i the estimate of firm unobserved fixed effects obtained
182
MIRELLA DAMIANI AND ANDREA RICCI
from the first step (Eq. (1)), PRP and U are dummy variables indicating, respectively, the presence of PRP and unions at firm level, and X is a vector of other control variables. The vector of coefficients dy, a0y , and Zy are estimated at the selected quantile; the idiosyncratic error term, ui, is such that Qy(ui|PRP, U, X) ¼ 0.5 In our framework, coefficients dy and a0y capture the quantile treatment effect of PRP and union presence across the distribution of the estimated firm specific unobserved heterogeneity. By verifying whether estimated coefficients d0y a0y differ across the quantile distribution of a^i , we can then infer how these labor market institutions affect firms’ unobserved fixed component. It is worth noting that the fixed effects, estimated in the first step, can be interpreted as average firm-specific differences in productivity predicted on the basis of variable inputs – in other words, as the TFP. The estimated fixed effects for the period 2002–2005 indicate whether firms’ TFP was below or above the average of the other firms during the observation period. Hence, with quantile regressions, we can infer whether for the key variables we obtain different coefficients across the distribution of the average TFP. The other control variables included in the baseline specification of Eq. (2) are the same used for descriptive statistics and includes variables that are standard in the related literature (see e.g., Bastos et al. 2009; Gu¨rtzgen, 2009). Estimations control for worker and firm heterogeneity, that is for a number of other potential determinants of productivity including the socioeconomic characteristics of an individual (such as gender), and membership three occupational groups (managers and supervisors, white- and bluecollars). We also control whether an individual is employed on a fixed term contract and is trained. The hypothesis is that the heterogeneity of workers (differentiated by gender, tenure, and skills) will influence the relationships we are testing. The group of firm characteristics includes size (interpreted, as suggested by Gu¨rtzgen, 2009, as capturing some part of unobserved firm quality and technological differences) and a group of variables related to strategies: capital accumulation, internationalization, innovation. Internationalization, proxied by a dummy variable indicating whether the firm sells its products abroad, controls for pressures on firm strategies exerted by international competition (Melitz, 2003). Other controls, such as local unemployment and vacancy rates, capture the role of labor market tightness and outside options that are expected to influence employee effort, as predicted by efficiency wage models. Estimations also control for unobserved sector characteristics and all regressions include eight industry-dummies corresponding to the
Performance-Related Pay, Unions, and Productivity in Italy
183
manufacturing and services sectors, defined at the two-digit level. In addition, the regressions include four dummies for geographical macroareas to take into territorial disparities in industrial relations, which are very important in the Italian economy.
ESTIMATION RESULTS This section presents the main econometric results. It should be emphasized that our two-step approach does not consider any endogeneity at the second-step level: firms’ decisions to adopt PRP and the presence of unions may be related to productivity performance. The occurrence of such reverse causality may generate biased estimates of quantile regressions, and we interpret the econometric results as simple correlations between the unexplained part of productivity and labor market institutions. Auxiliary estimations of the determinants of the adoption of PRP schemes, obtained by using a probit model, offer additional insights and are reported in the Appendix (Table A2).6 The estimates of the marginal effects show that gains in productivity in preceding years increase the probability of adoption of PRP, and these marginal effects are higher for the group of high performers. Internationalization, unionization, training, and gender composition are significant predictors of the probability of PRP, thus confirming that the two groups of firms (PRP and non-PRP) are very different.7 As mentioned earlier, to estimate the PRP–productivity relationship, the first step consists in estimating Eq. (1) for the unbalanced panel of firms sampled for the period 2002–2005 with a within-estimator. In the second step, quantile regressions were applied to Eq. (2) to estimate the coefficients for PRP and unions at different points of the firm-specific fixed effect distribution, that is, at the 0.10th, 0.25th, 0.50th, 0.75th, and 0.90th quantiles. Columns 1–2 of Table 3 report the estimated coefficients of the production function (1). The first-step estimates of the fixed capital and number of employees have the expected signs and high statistical significance. We will not comment further on these results, as our focus is on the OLS and quantile estimates for the second-step regressions (columns 3–11 of Table 3). The principal result is that the estimate of PRP is positive and statistically significant (error level of 1%) across the whole distribution, in line with the results obtained for the Italian metal-working sector (Biagioli & Curatolo, 1999;

Origo, 2009). We also find that the point estimates of PRP are fairly uniform across the distribution, ranging from 0.17 at the 10th and 75th quantiles to 0.22 at the 90th quantile. As mentioned earlier, the estimated coefficients can be interpreted as the partial derivative of the conditional quantile of the estimated fixed effect a^i (i.e., TFP) with respect to a particular regressor, that is qQy(ai|PRP, X)/qX. Then, for instance, the estimated coefficient of 0.17 is the marginal change in a^ i at the 10th conditional quantile due to a discrete change (from 0 to 1) in the adoption of PRP, while the estimated coefficient of 0.22 is the marginal change in a^i at the 90th conditional quantile. A similar interpretation holds for other quantile estimates and other regressors. Furthermore, given that the estimated fixed effects indicate whether firms’ TFP is below or above the average productivity of the other firms over the period 2002–2005, the results in Table 3 show the role of PRP in filling the gap with respect to the productivity average for low achiever firms or, conversely, in increasing the gap for over achiever firms. The positive and significant estimates of unions are also worthy of note. A feasible explanation is that their presence minimizes free-riding and promotes collaborative attitudes. However, the positive coefficient of the union dummy variable increases significantly at the highest quantiles, being 0.24 in the 1st and 0.30 in the 75th and 90th quantiles.8 These results may be explained by arguing, as suggested by Addison and Hirsch (1989, p. 76), that ‘‘union and non-union establishments may differ systematically in the quality of unmeasured organizational factors, so that firm effects are not independent of union status. For example, inputs such as managerial supervision and the quality of labor relations may be correlated with unionism, and omission of these factors may bias the union coefficient.’’ Table 3 also shows other findings related to workers’ characteristics, such as employment positions: the coefficient associated to the white- and bluecollar components is negative and significant, mainly at the highest quantiles (with respect to the omitted category, i.e., managers and supervisors). A plausible interpretation is that managerial employees have a positive and significant influence on productivity, especially in better-performing firms. Among other factors, this may be due to their providing better-designed pay schemes to induce optimal effort from their subordinates. As for the other results, the strong negative coefficient associated with the percentage of women (with a decreasing pattern along the distribution, which varies from 0.48 at the 10th quantile to 0.19 at the 90th quantile) should be noted. A cautionary interpretation is necessary, since the percentage of women is very likely to be correlated with unobserved
186
MIRELLA DAMIANI AND ANDREA RICCI
(or omitted) firm characteristics. The negative coefficient associated with the female component is likely to be related to the gender wage gap, more plausibly at the lowest quantiles of the wage distribution.9 Future research, based on additional data, would certainly help to estimate the impact of the female component and to verify whether lower TFP is caused by less generous PRP offered to women. Another interesting finding is the negative coefficient of fixed-term workers across the whole distribution, with a magnitude that decreases at higher quantiles and becomes statistically insignificant at the 90th quantile. Conversely, the estimated coefficient of trained workers is positive, but significant at only 1% for the intermediate value of the distribution. Lastly, our estimates confirm that size and the geographical location of firms are important factors related to their efficiency. The positive relationship between firm size and TFP is significant at all quantiles. As expected, we have regional gaps, as shown by the positive coefficients for Northern and Central firms (with respect to Southern firms, the omitted category), although the estimates do not show a clear pattern across the distribution.10
MANUFACTURING AND SERVICES SECTORS The role of firm and sectoral disparities are examined in this section. To ascertain whether the relationship between labor institutions and TFP depends on firm sectoral specialization, we replicated the preceding analysis for the manufacturing and services sectors, separately.11 The econometric strategy and estimation methods are the same as those used for the whole economy, and do not require further explanation. Table 4 displays the results for manufacturing. The second-step estimates confirm the positive and significant coefficient of PRP and unions across all quantiles. However, the magnitudes of the estimated coefficients for both variables are higher than those found for the whole economy, and are fairly uniform across all quantiles. The analysis of the professional composition of the workforce yields no clear interpretation: the coefficients associated with the share of blue- and white-collar workers are positive at the 10th quantile and negative at the 75th quantile, but are not statistically significant at the other quantiles. The coefficient for trained workers is positive across the whole distribution, except at the 90th quantile, while that of fixed-term workers is negative and its absolute value is higher at the 75th and 90th quantiles.

size and geographical location in industry are similar to those found for the rest of the economy. The estimates for services show high standard errors, probably due to the small number of service firms using PRP. However, since this is the first time that information on this sector of the Italian economy has been available, we have chosen to report our findings, albeit preliminary. The main difference respect to the manufacturing sector is that in services we have a positive, significant, coefficient of PRP only at the 25th and 50th quantiles (Table 5). Our estimates thus suggest that the productivity–PRP link in the services sector is less evident. It is a critical aspect for a laborintensive sector, where promotion of organizational changes and wage policies to motivate employees are expected to enhance TFP growth. The union dummy variable continues to be positive and significant across the entire distribution, with a higher coefficient at the 75th and 90th quantiles (around 0.30). Interestingly, trained workers play no significant role, whereas estimates for fixed-term workers are negative at all quantiles of the distribution. For over-performer companies, we also find that the coefficients of whiteand blue-collars are negative and significant (with respect to managerial and supervisory staff, the omitted group). These effects are more noticeable in firms characterized by low and medium productivity increases. This last finding also suggests that management counts more in a sector like the tertiary, where production processes are the result of the intangible competences of human capital.12 Lastly, our estimates show that location in Northern regions and size also promote productivity growth in the services sector, as found for manufacturing. One probable reason for the importance of the role of size is that larger firms are expected to be associated with superior managerial competence. The latter is an omitted variable which could perhaps be proxied by size. Indeed, the best performers (represented by larger firms) can afford costly strategies such as the upgrading of management: this leads to the implementation of better practices which in turn produces greater efficiency. In addition, in large companies, economies of scale reduce implementation costs per employee and explain why benefits are likely to exceed costs. Our results, in any case, call for further investigation of the role of managers in establishing a climate of successful cooperation with workers and their representatives. The analysis of the interactions between PRP and high-performance work practices would allow us to verify the importance of the ‘‘high commitment’’ strategy, based on worker participation and involvement, as found in other studies (see Ichniowski et al., 1997).

CONCLUSIONS Our estimates suggest a positive and significant relationship between PRP and productivity in both under and over achiever firms. Our other main finding concerns the positive and significant role of the presence of trade unions. For this variable, estimates for the whole economy show that significant differences exist between firms: in overachiever firms, unions, which minimize free-riding behavior and promote cooperative attitudes, have a higher correlation with productivity. Other findings concern workers’ characteristics. A greater presence of managers is significantly related to productivity, especially in firms with better performances. One probable reason is that the best performers can afford costly strategies, such as the upgrading of management, who then provide better designed pay schemes with the aim of inducing optimal effort from their subordinates. We also find a negative relationship between productivity and the percentage of fixed-term workers, while the opposite is true for the proportion of trained workers. Our research also finds a considerable gap between sectors: higher significant estimates of PRP agreements are found for firms operating in manufacturing industries, uniform along the whole productivity distribution. In the services sector, no significant coefficients are obtained for any groups of firms. It seems likely that the limited implementation of PRP practices or their use as a rent-sharing device may partly explain the slowdown in Italian productivity, mainly due to the bad performance of services. The main limitation of our findings concerns the possible endogeneity of institutions and human resources management, perhaps due to firm productivity. Future research will explore this issue by exploiting the second wave of the RIL survey, which allows longitudinal tracking of the adoption of PRP and the presence of unions at firm level. In this perspective, we will also attempt to evaluate whether employee financial participation is a valid strategy, especially in unionized Italian companies. It may be an additional step in detecting the reasons behind the successes and failures of Italian firms.

profit-sharing, and worker ownership for Italian producer cooperatives, one of the largest systems of producer cooperatives in industrialized Western countries. 3. For a discussion of the experience of employee financial participation in Western and Eastern new EU member states, see Uvalic (2006). 4. In particular, we group two-digit sectors into eight categories: (1) mining and quarrying, electricity, gas and water supply; (2) manufacturing; (3) construction; (4) trade, hotels and restaurants; (5) transport and communications; (6) financial intermediation; (7) other business services; (8) education, health and other public services. 5. For a detailed discussion on methodological issues and techniques used to perform point and interval inferences, see Buchinsky (1994) and Koenker and Bassett (1978). 6. In our probit estimates, the distribution of average firm residuals over this period and by different quartiles are used as regressors of the probability of PRP. Note that the vector of control variables does not include the firm size. This is because in the first step we estimate the average firm residual by controlling for firm size in the production function (see Eq. (1)). 7. The existence of a virtuous cycle between PRP, unions, and firms’ productivity has been explicitly verified by probit estimates, see the Appendix, Table A2. 8. It means that the relationship between unionization and the firm specific unobserved heterogeneity of productivity increased from 0.24 to 0.30. Note that the null hypothesis that the estimates are equal between pair-wise quantiles (and across all quantiles) is tested by the variance-covariance matrix of the coefficients of the system of quantile regressions. Consequently, the null hypothesis about the union dummy variable is rejected at the conventional level of significance for the 0.10 vs. 0.90 quantiles; conversely, the null hypothesis of equality of the coefficient of the PRP variable is accepted across the entire distribution. 9. The ‘‘sticky floor’’ hypothesis, i.e., a larger gender pay gap at the bottom of the distribution, has been proposed by Booth (2009) and estimated for Italy (Naticchioni & Ricci, 2009) and 11 European countries, Italy included (Arulampalam, Booth, & Bryan, 2007). 10. Given our focus on institutions, we do not comment on other significant estimates of quantile regressions, the positive role exerted by firms which compete on international markets, and the negative impact of the vacancy rate variable. Both results deserve future study. 11. In particular, the manufacturing sector includes: mining and quarrying; electricity, gas, and water supply; manufacturing; construction. The service sector includes: trade, hotels, and restaurants; transport and communication; financial intermediation and other business services; education, health, and other public services. 12. In another study on Italian manufacturing firms, Piva, Santarelli, and Vivarelli (2005) have shown that organizational improvements, combined with technological innovation, jointly affect the demand for labor and skills, proxied by white- and blue-collar shares.

PART III WORKER COOPERATIVES AND NONPROFIT ORGANIZATIONS
PROFIT REINVESTMENT IN ITALIAN WORKER COOPERATIVES AS A CONTRIBUTION TO A COMMON GOOD: AN EMPIRICAL ANALYSIS ON WORKERS’ PERCEPTION AND MOTIVATION Cecilia Navarra ABSTRACT Italian worker cooperatives display a high proportion of profits reinvested into asset locks: there is some literature investigating their function, but little has been said about workers’ attitude toward them. In this chapter we therefore investigate what workers’ motivations are regarding reinvesting profits into asset locks. We propose to interpret them as a common good and we inquire which factors may increase workers’ willingness to contribute to it. We test two arguments that are provided in the literature on collective action: the effect of having a long-time perspective within the cooperative and the effect of displaying ‘‘collective’’ motivations and preferences other than self-regarding. We perform this test by means of a survey among workers of cooperatives affiliated to Legacoop Ravenna in Italy.

We identify a positive effect of both factors, although with some distinction. At a first glance, we find a positive correlation between a longer time horizon and a greater concern for profit reinvestment; when looking closer at the data, we nevertheless see a more complex relationship as two other aspects come into the game: the employment insurance role of worker cooperatives and the ‘‘feeling of belonging’’ that links workers to the firm. The positive effect of this second aspect on the willingness to reinvest into locked assets is strong, although it only appears among worker-members. Moreover, its effect seem to become greater as workers’ involvement in decision making increases. Keywords: Worker cooperatives; asset locks; common good; workers’ motivations JEL classifications: J54; J28; D64; D71
INTRODUCTION Italian worker cooperatives display a peculiar feature: a high proportion of profits are reinvested into asset locks, a common fund that is not appropriable and not divisible among members, neither on member’s retirement, nor at the end of the life of the cooperative. Our first claim is that asset locks may be qualified as a ‘‘common pool resource’’ and the contributions to this pool may be interpreted as contributions to a common good. Asset locks are indeed not individually appropriable and they may only be used for the firm’s overall purposes. These different uses bring about mutual rivalry, but the benefits produced are not excludable. Therefore, we presume that a problem concerning collective action may come up. This may appear in two forms: first of all, there may a free rider problem in effort provision on behalf of individuals. Profit reinvestment into such a nondivisible and nonappropriable fund may indeed be inefficient from the incentives point of view. The second problem is an intertemporal one: the members of each generation may be tempted to behave opportunistically with respect to future generations, and opt for a high degree of profit distribution today, as the choice to accumulate will prevent them from having access to those assets tomorrow. Decisions concerning asset locks are, thus, both individual decisions about participation in the creation of a common good through effort provision, and collective decisions regarding

the allocation of profits to this ‘‘common’’ and their assignment to parts of it for alternative uses. Although a debate flourishes in the literature discussing their function, little has been said about the workers’ perception of asset locks. In this chapter, we intend to investigate what the individual characteristics are that increase the willingness to reinvest profits into the firm. We investigate the determinants of a positive attitude toward the indivisible accumulation of capital, considering this attitude as a measure of the extent of ‘‘cooperation’’ among members in the collective action. These individual features may be both motivational elements that introduce preferences other than self-regarding, and characteristics concerning the time perspective of each member within the group. First of all, we intend to present the profit allocation mechanism briefly as regards asset locks and a short literature review on their possible functions. Then, we will introduce two arguments that have been put forward in order to explain how cooperation can emerge as a dominant strategy within groups: on one hand, the time horizon of group members and the discount rate of future benefits, taking inspiration from the work of the Nobel laureate Elinor Ostrom (1990), and, on the other, the intervention of some mechanisms of self-recognition of members as part of a ‘‘collective agent’’ (Bowles & Gintis 2006; Hollis & Sugden, 1993). We have strong historical evidence, indeed, that a major role is played by the path of cohesion within the group that forms the cooperative (Menzani, 2007; Nardi, 1998; Navarra, 2010). In the final part, we will try to apply these two arguments to the choice of collective investment, by means of an empirical investigation carried out in the workers’ cooperatives associated with the Lega delle Cooperative e Mutue in the province of Ravenna (Italy), using a dataset constructed through an original survey among a sample of workers, integrated with historical evidence and qualitative interviews of the cooperative board members. We will conclude with some reflections on the determinants of the positive attitude toward asset locks and on the validity of the aforementioned arguments in our case study. As we will discuss, our findings are consistent with both arguments, although with some distinctions: the positive opinion on asset locks is nonmonotonic with respect to the time perspective of workers inside the cooperative, and the higher loyalty to the firms that reinvest a greater share of profits can be interpreted in multiple ways. The positive interplay of the preference for profit reinvestment and the feeling of belonging to the cooperative is strong, but only applies to worker-members. Finally, a possible role for the employment protection function of the cooperative enterprise is highlighted.

ASSET LOCKS IN ITALIAN WORKER COOPERATIVES Asset locks (riserve indivisibili) are a common fund that is nondivisible and nonappropriable by members, that is accumulated through the assignment of a yearly profits share that is decided at the end-of-the-year assembly, where all members vote the board’s proposal on the subject. Once profits have been allocated to this fund, they become part of the cooperative’s assets and may only be used for a firm’s overall purposes, such as new investments and the introduction of innovations. They may be used to recover from losses, but only after having used other divisible funds and with the obligation of their immediate refunding. As regards profit allocation, the limitations imposed by law are to allocate 30% (20% until 2003) of profits to the legal reserve (again, not divisible and not appropriable), and 3% to fondi mutualistici, that are solidarity funds used to support the cooperative movement as a whole. Besides these limitations, profits may be distributed to members in two main ways: as a remuneration of capital stakes (within strict limitations imposed by law), or as a remuneration for the work relationship (the so-called ristorno). Since 2001,1 a second form of distribution has been introduced, that is by increasing individual capital quotas, in order to distribute profits and avoid the risk of undercapitalization of the firm. Moreover, since 2003,2 cooperatives have been able to accumulate divisible reserves that can be appropriated by the ‘‘financial members,’’3 allowing the asset owned by these members to internalize the increases in firm’s profits, thus becoming more attractive. Up to some years ago we would have argued that asset locks were the only tool for the cooperative enterprise to accumulate capital, but this is no longer the case today. Nevertheless, there is evidence that Italian worker cooperatives reinvest a huge amount of yearly profits into asset locks: a study of the Centro Studi Legacoop (2006) shows that, on average, 86.8% of net profits is reinvested in the firm and 10.2% is distributed to members. This evidence is confirmed in the literature on the Italian cooperative movement (Bassi 2003, Zevi 2003) and by the data of our case study, as we will illustrate in the following pages. These data show an average share of profit reinvested into asset locks that is clearly above the amount required by law.4 How can we explain this choice? One of the usual arguments to explain this huge reinvestment is the advantage of indivisible accumulation from the point of view of corporate tax. However, we do not think that this is a

203
crucial reason: if it is true that there is a fiscal advantage as far as asset locks accumulation is concerned this has sharply declined over the last few years,5 but the average share of reinvested profits did not follow this decrease and – at least in our case study – remained almost constant over time (Navarra, 2010). One possible alternative explanation is to assume that asset locks have a collateral function that prevents the firm’s capital stock from being exposed to huge capital variability (Tortia, 2002): this may explain why weaker firms choose to reinvest a higher share of profits in asset locks (Jones & Svejnar, 1985) and why the same is done by smaller firms (Centro Studi Legacoop, 2006). In other works, we focus on another possible argument so to explain the function of asset locks, that relates to the employment insurance role of worker cooperatives: cumulated indivisible capital may be seen as a possible tool for worker members to insure themselves against the risk of losing their jobs and, at the same time, to stabilize wage earnings (Navarra, 2010). Sacconi and Seppi (2006) argue that asset locks (or, rather, reserve indivisibility as a norm) may be interpreted as a governance device for members to ‘‘tie their hand’’ so as not to have the incentive to behave opportunistically toward future members. The authors claim that the indivisibility of the firm’s assets in cooperatives may be interpreted as a tool to produce the dynamics of the indefinitely iterated game, that is indeed able to make the agents converge on the cooperative equilibrium and avoid free riding (that on the contrary would be a risk if members could withdraw their quota of the firm’s reserves ad lib.). We do not intend to put forward arguments that conflict with the aforementioned; in this chapter we propose another perspective regarding this issue. Although the previous arguments explain asset locks through their function, we have tried to approach the issue from the point of view of workers’ motivation. Moreover, those explanations include a ‘‘common good’’ component: the function of asset locks as a collateral, as an insurance tool, or as a governance device, all include a collective component that is not directly appropriable by individuals. This means that a certain amount of cooperation is needed to achieve all those purposes by means of indivisible accumulation. This is the reason why we investigate what influences the attitude of workers of cooperatives toward this form of profit reinvestment. We start with a theoretical introduction to those motivational elements that may enhance cooperation among members of a group in the pursuit of a common aim that requires the renouncement to an individual and immediate gain.

A THEORETICAL FRAMEWORK ON PROFIT REINVESTMENT AS A COLLECTIVE ACTION: HOW TO ENHANCE COOPERATION If we consider asset locks as a common good, theory tells us that a risk of opportunistic behavior is likely to emerge. As claimed in the seminal work by Mancur Olson (1965), when a group of people share the same interest in order to obtain a good that is, in their perspective, a public good, therefore nonexcludable, there is the risk that they may ‘‘rationally’’ choose not to contribute to its production (each one will not be excluded from the benefits and has no incentive to bear the cost of its provision). If that is so from the part of all members, the common good will not be provided (the so-called risk of ‘‘collective action failure’’). As we have already mentioned, the problem concerning collective action may be twofold: first of all, an incentive problem at an individual level in effort provision and, secondly, the risk of opportunism in the current group of members, that may opt for maximising their short-run income by profit sharing, instead of reinvesting profits into asset locks. As regards the first, cooperatives differ from the capitalistic firm, where the risk of free-riding in teams is reduced by the fact that one individual takes control of the activity of the others, as claimed by the ‘‘Property Rights School’’ (Alchian & Demsetz, 1973; Demsetz, 1967; Jensen & Meckling, 1979): he is entitled to monitoring and has efficient production incentives (given by his residual claimancy), whereas the others act on his behalf and under his control. On the contrary, cooperatives are what Elinor Ostrom (1990) would define as a ‘‘group of principals’’ (Navarra & Tortia, 2010), that is an organization where no one loses his control power and where the firm’s assets are a common good. What does the literature on collective action say about the factors that may allow a group sharing a common interest to avoid the outcome that is illustrated by Olson?
Time Horizon of Members: Indefinitely Iterated Games and the Long-Term Work Relationship One factor that may allow cooperation to emerge as a dominant strategy within groups is the length of the time horizon of members’ interaction. A longer time horizon, that is the perspective of a stable interaction among

205
members in the future, following Elinor Ostrom (1990), allows for reputation mechanisms to arise and the importance given to future benefits to increase. Within the case studies carried out by Ostrom, the more successful groups in common resource management are those marked by the stability of the referring population. The importance given to belonging to the group and to the reputation within it have the effect of lowering the discount rate of the flow of future benefits that derive from the common resource. This mechanism, together with a pattern of credible sanctions, has the effect that group members make long run gains due to participation greater than short run gains that may be obtained from defection (Platteau, 2004). The time horizon of members inside the cooperative is a customary argument claiming the inefficiency of this kind of firm (Furubotn & Pejovich 1970; Jensen & Meckling 1979), as it implies that workers will behave in order to maximize nearer term cash flows6. If we adopt the collective action perspective, the subjective time horizon of members’ interaction may be one of the ways out for the impasse of collective action failure. If we allow for repeated interaction among agents, the importance attached to the possibility of being part of the group tomorrow (and therefore having access to the common good) increases. Within the context of worker cooperatives, this can be translated into two ways. The first is proposed by Sacconi and Seppi (2006), who argue that the indivisibility of the cooperative’s assets may be interpreted as a governance device in order to produce the dynamics of the indefinitely iterated game. Therefore, asset locks are an instrument that allows the cooperative to establish the rules to generate a game where it is rational for all the agents to play the cooperative strategy, as they participate in an interaction that potentially repeats itself after each play. This makes the free rider option less rewarding than the choice of continuing to cooperate. As regards capital accumulation, conflict among generations may arise, where older members have the tendency to free ride, because of their short-time horizon within the cooperative; thus, if they prevail, the reinvestment of profits will be suboptimal. Conte and Ye (1995) propose a model where different generations have the possibility to enter into a binding agreement that the authors formalize as a system of transfer payments; the outcome of their model is that the cooperative will reach the same steady-state capital stock as the ‘‘twin’’ capitalistic firm. If we follow Sacconi and Seppi’s suggestion, we may argue that a similar role may be played by asset locks. These can be interpreted as a way for the insiders to decide – as long as they have the incentive to do so – to ‘‘tie their hands’’ referring to the capital they will be tempted to withdraw tomorrow.

The second argument relates to the evidence that cooperatives manage to have a more stable workforce than comparable capital-managed firms (Bartlett, Cable, Estrin, Jones, & Smith, 1992, for example, show that cooperatives display lower quit rates) and guarantee more stable employment relationships. This expands the time horizon of workers inside the firm, therefore increasing their willingness to reinvest profits into it. This can be even stronger if the incumbent member of the cooperative thinks that his children will work in the same firm as he does. If we find evidence of an intergenerational perspective, it can represent likewise a strong investment incentive and an instrument to avoid free riding toward future members of the cooperative.
The ‘‘We-Rational’’ Attitude of Members: Collective Aims and Feeling of Belonging Major authors claim that interpretations in terms of self-regarding preferences are not sufficient to shed light on many aspects of economic life. Bowles and Gintis (2006) clearly state that they are not satisfied with a theory of choice that only allows for reciprocity if interaction takes place in a repeated game framework. They claim that we have to account for the capacity of people to internalize moral norms and to enter into relationships marked by some feeling of belonging. Akerlof and Kranton’s (2005), for instance, analyze how noneconomic concerns (identity) come into economic dynamics: if an agent identifies himself as an insider, he will require lower monetary incentives to do his job. His identity comes from his belonging to a social category, that is not the result of a rational choice, but rather of a ‘‘framing’’ process with regard to ‘‘a person’s self-image as an individual and as a part of a group’’ (Akerlof & Kranton, 2005, p. 1). These approaches therefore raise criticism, as expressed by Hollis and Sugden (1993), about instrumental rationality and strategic interaction models. They argue that these do not leave any ‘‘room for reflection’’ between utilities and rational choices: every motivating factor only works as a source of utility and can have no role once utilities are identified. The attempt would be to give a role to personalized interactions, in order to account for a more complex idea of transactions, and not to scale them down to exchanges (Gui, 2005). This alternative approach that gives new weight to the social context of an action has clear implications in the problem of public good provision. The basic theory on public goods implies that the quantity provided will fall

207
short of the efficient level, as each contribution is considered to be a perfect substitute for the others and this implies mutual crowding out of contributions. As Bardsley (2005) points out, we need other approaches to account for the amount of empirical evidence that shows, on the contrary, a crowding-in effect among contributions. He particularly stresses in two concepts that reject mere instrumental rationality: expressive rationality and collective rationality (also Hollis & Sugden, 1993). Expressive rationality implies that an action is not rational in sight of some end (a payoff), but it is rational as it expresses attitudes or principles that have, as regards the agent, the role of realizing his identity. If agents are concerned about the meaning of their actions, not by their consequences, the constraints on actions are not simply given by the specific current interaction, but by the attitudes prevalent in the community. In this sense, contributing to a public good may be a statement of value and therefore judged irrespectively of the payoff it generates. Collective rationality, in a related way, introduces the possibility for people to agree on what is good for them as a group. It means first of all that people can act as collective agents: it becomes rational to act as a part of the group and to take the existence of a ‘‘team-optimal’’ plan as a reason for action. Moreover, in this case, members’ expectations regarding the behavior of others’ are derived from their team membership, not from strategic reasoning. On what concerns worker cooperatives, the observed big amount of profit reinvestment into asset locks represent a direct cost for the individual that is translated into a common good, whose benefits for the individual are strongly diluted within the group of members and over time. We thus introduce the possibility that workers’ motivations go beyond instrumental rationality, in order to account for the fact that individuals may incur net costs, for the benefits of the whole group. The investment into asset locks can be interpreted, on one hand, as deriving from a set of ‘‘normative expectations’’ (Sugden, 1998), that is the mutual expectation to follow a norm and disapprove of breaching it, regardless of the payoff it has for each individual, On the other hand, it can be interpreted as an expression of ‘‘we-rationality,’’ or team-thinking (Hollis & Sugden, 1993), that is, by assuming that what is rational for the individuals is to behave consistently with their belonging to the group. We therefore search for some evidence of these mechanisms, by using our survey data: are there any people who think that it is right to allocate net profits to asset locks and therefore follow this rule, instead of rationally calculating their payoff under different allocation of profits? Another question to be raised is whether there is a form of strategic interaction
208
CECILIA NAVARRA
between the workers and the firm. The idea is to understand whether the worker ‘‘punishes’’ the cooperative by opposing profit reinvestment into asset locks, in case the firm does not match his expectations. Last of all, we investigate the existence of a feeling of belonging to the cooperative and the effect that this may have on workers’ attitude toward the indivisibility of firm’s assets and the lack of profit distribution. It has to be said that the possible function of the cooperative enterprise as an actor of social cohesion and solidarity is documented in the historical literature. The role of cooperatives as solidarity networks has been a major issue since the beginning of the cooperative movement, particularly in the case of Romagna, where the first groups to be formed were made up of the weakest categories of workers: as Zangheri, Galasso, and Castronovo (1987) underline, the central feature of the first land-workers’ cooperatives was mainly the capacity of solidarity, rather than economic performance. An interesting factor that is widely underlined by historians is the capacity of the cooperative to provide collective goods for the community: holidays for members’ children, activities for the elderly, social insurance mechanisms such as internal pension funds to integrate retired members’ incomes, and cultural activities. These solidarity actions were likely to be sustained even in hard times when the members themselves might have received lower wages (Tampieri, 1967).
INDIVIDUAL CHARACTERISTICS OF MEMBERS AND THEIR OPINION ON ASSET LOCKS: THE EMPIRICAL ANALYSIS The Survey: Lega delle Cooperative e Mutue of the Province of Ravenna The survey was conducted in 2007 by the author within 18 of the 60 worker cooperatives affiliated to the Legacoop in the province of Ravenna, Italy. Questionnaires were submitted to workers (both members and non members) for a total of 415 observations. The sector repartition is the following: 87 questionnaires from agriculture, 95 from construction, 52 from manufacturing, 52 from porters’, and 129 from other services. Around 80% of the samples are worker-members, whereas 20% are employees; 40% women; and 66% blue collar. Qualitative semistructured interviews were conducted in the same firms together with the president or a board member.

The survey data is matched with firm-level data based on balance sheets accounting. There is a long history of cooperative movement in the Ravenna region (Romagna). At the end of the nineteenth century the first cooperatives of day land-workers were funded, closely followed by the construction ones. Employment protection was a major concern (Sapelli & Zan, 1971), and it is still, even today (Navarra, 2010). The population of Legacoop Ravenna worker cooperatives confirms the high tendency to profit reinvestment into asset locks displayed by the Italian cooperative movement: the average share of yearly profits accumulated into asset locks is nearly 88%, and more than 60% of them reinvest between 90% and 100% of profits into the indivisible fund.
The Time Horizon Perceived by Members and Their Attitude Toward Asset Locks Our measure of members’ perception of the duration of their relationship with the cooperative includes both the individual perspective and the intergenerational one. In the first case, we look at the time that has already been spent in the cooperative and at the subjective perception of people about their permanence in it. The second one has two components. On the one hand, the backward-looking perspective: did any of the respondent’s family work in the cooperative before he did? On the other hand, the forwardlooking one: does the respondent expect that his children will work in the same cooperative as he does? As regards the individual time dimension, cooperative workers have the perspective of long permanence within the firm. The average time spent in the cooperative among the respondents is around 13 years, but may vary in different sectors.7 If we look at the frequency of contract typologies, we can find a very skewed frequency table, where 70% of interviewees have a nonfixed term employment contract.8 The subjective perception of the future time permanence in the firm provides striking evidence, as may be seen in Table 1. Only 14% of the interviewees think they will leave in about 5 years time, whereas 72% think they will stay at the cooperative until they retire. This is a very mixed indicator as it captures workers’ satisfaction, age, employment stability, and outside options at the same time. It gives nevertheless a flavour perception of stability within the cooperative. As we have already argued, the sectors where the life-long employment pattern is more diffused are

agriculture and construction, where about 80% of respondents declare they expect to stay for their whole working life. If we look at the intergenerational perspective, the backward-looking dimension is captured by a dummy variable (‘‘family’’ dummy), that has a value of 1 if the respondent has at least one member of his family who worked at the same cooperative before he did (a little more than 26% of respondents).9 The third component is the forward-looking one: a dummy variable (‘‘children’’) is generated from two questions, where workers were asked if they would like their children to work at their cooperative and whether they think that it is likely to happen: 19.8% of respondents expect their children to work in the cooperative.10 The time horizon is therefore long in terms of a single generation, but it does not extend to future generations11 to the same extent. Concerning the difference among members and employees,12 we notice that the latter show an average permanence in the firm (6 years) that is lower than the former (15 years); they also display a lower perception of future time horizon, but keep the same pattern as members: if among members 78% of respondents think they will stay at the cooperative until they retire, this percentage decreases to 51% among employees but as regards this question it is still the option they select the most. When asked if they would move to a capitalistic enterprise, more respondents among employees, with respect to members answered that they would if they were offered a higher wage or a better position, and less of them refused a priori this option (17.5% among employees and 33% among members). This is consistent with the information obtained through qualitative interviews with board members, where it was often underlined that it is usually a choice of the worker himself not to become member, as it implies both a monetary investment in the cooperative, and a choice of long-term relationship with the firm.13 We now inquire the relationship between the time horizon of workers and the attitude to collective accumulation of capital, that is the choice of
Profit Reinvestment in Asset Locks: Workers’ Motivations
211
renouncing to an individual use of profits today, in favour to a collective use tomorrow. Concerning the opinion on collective accumulation in the questionnaire, workers are directly asked to give their opinion on asset locks (see Table 2, column a). It is clear that a positive opinion is prevalent, first of all motivated by the firm’s solidity, secondly by a moral concern regarding fairness. Workers were also asked to indicate their preferred destination of profits (Table 3, column a). Two answers are dominant: profits shall be kept in the cooperative in order to strengthen it, and profits shall be distributed to members, but only in good times. On looking at the whole picture, the opinion regarding profit reinvestment and asset locks accumulation seems to show a time horizon effect in both questions: if we split our observations among those workers who have a time horizon lower than 5 years within the company, and those who have a higher one, we can see that 66% of workers in the first group have a positive opinion regarding the indivisible accumulation of capital and 39% believe that profits should be kept within the firm. In the second group, these percentages rise to 76% and 46%. Nevertheless, if we present the answers in a more detailed way, the picture becomes more mixed. If we look at the opinion table on asset locks, disentangled by the time expected to be spent in the cooperative, we will find some mixed evidence, as we can see in Table 2 columns (b–e). Among those who think they will stay in the firm until they retire, more than 80% of respondents believe that asset locks are either necessary or fair. Furthermore, a similar distribution can be found among those whose time perspective is between 2 and 5 years as well. Moreover, 55% of respondents in column b (those who think they will stay at the cooperative for less than 2 years) say that asset locks are necessary in order to strengthen the enterprise: they consider the solidity of the cooperative important even though they are not likely to have any advantages, given the short run projection they have in the cooperative. A more straightforward picture emerges if we consider how people answered the question relative to the preferred destination of profits (Table 3, column b–e): among the ‘‘short-time-horizon’’ respondents, profit distribution is preferred on the whole. The argument concerning the firm’s strengthening becomes more frequent when we look at the ‘‘long-timehorizon’’ members, making profit reinvestment becomes more attractive: workers who think that they will have a longer relationship with the cooperative are more concerned with its solidity.

If we look at the effect of the intergenerational link, we find out that this increases the importance given to fairness. The positive opinion on indivisible profit reinvestment as they are ‘‘fair’’ (including the concern for future generations) has a greater weight if the respondent expects his own children to work in the same firm as he does. The same result can be found by disentangling these opinions by the ‘‘family dummy.’’ Here, the increased importance given to ‘‘fairness’’ regarding the indivisibility of asset locks is even higher. This is confirmed by qualitative evidence: the cumulated assets by reinvesting profits are considered to be the inheritance that has been left by previous generations and this is the reason why it has to be indivisible.14 When asked what should be done with firm profits, the ‘‘solidity argument’’ is more relevant among those who have a longer projection in the enterprise: looking at the answers relevant to the question disentangled by ‘‘children dummy,’’ we can see that the two groups display similar patterns, but the respondents who think (or hope) that their children will work in the same firm as them have a greater concern for the solidity role of profit reinvestment in the enterprise. If we try to understand whether the accumulation policy of the firm influences members’ time horizon, the evidence is mixed. By looking at the relationship between the current share of profits reinvested into asset locks and the percentage of respondents that have a long-time horizon within the firm (or project this on future generations) on the total number of questionnaires collected in each cooperative, we do not find any evidence of correlation; if we use an indicator of the cumulated (instead of current) asset locks, there is evidence of a positive correlation, but only in highly capitalized firms.15 A more accurate specification may be obtained by looking at the determinants of the number of years that workers have actually spent in the cooperative, where we can find a positive effect of the share of reinvested profits in the common fund (Table 4). Workers tend to stay longer in cooperatives that reinvest a higher share of profits into asset locks: this may be due to the fact that asset locks actually work as an incentive device in order to increase the willingness of workers to stay. This result is not unambiguous, it can also be explained by the fact that firms that reinvest a greater share of profits are more able to guarantee workers employment stability. Moreover, we find a mixed effect depending on the size of the cooperative: if measured by the number of workers, it has a negative effect (bigger cooperatives may have higher turnover), but the opposite is true if we

measure the size of the cooperative by the amount of share capital. Besides some intuitive results (the positive effect of age and membership), it is interesting to notice that education displays a negative coefficient, that may be due to the fact that more educated workers are usually younger and have more outside options. Having a relative working in the same cooperative increases the years spent inside it: the intergenerational projection on the cooperative seems to be a loyalty factor and possibly an element of ‘‘belonging.’’ To sum up, we may say that we have evidence of higher loyalty in firms that accumulate a greater share of profits in asset locks: however, it is difficult to disentangle whether it is a ‘‘time horizon’’ effect, or it is more likely to be due to an employment insurance mechanism that works through asset locks (Navarra, 2010). If we look at the time perspective perceived by interviewees, unambiguous evidence of the effect of the accumulation policy as a device to ‘‘extend’’ the time horizon in firms as perceived by workers is missing. It is obvious that this does not rule out the possibility that indivisibility as a norm may be interpreted as a device to avoid opportunism as far as future generations are concerned (Sacconi & Seppi, 2006). On the contrary, we find some evidence of a positive effect of workers’ time horizon on their opinion on profit reinvestment and asset locks. If we consider the
216
CECILIA NAVARRA
opinion expressed about the destination of the cooperative’s yearly profits, workers who have a longer time perspective seem to prefer profit accumulation as it represents a tool to reinforce the firm. Thus, if there is a longer permanence perspective in the cooperative, there may be a lower discount rate of future benefits deriving from the interaction with the firm, that partially translates into the willingness to reinvest profits into asset locks. If, however, we look at the opinion directly expressed on asset locks, there is no clear evidence of a monotonic effect of the time perspective, since we may find a positive opinion among members who plan to quit the firm relatively soon. There seem, nevertheless, to be a greater concern for fairness among those who have an intergenerational projection. This evidence calls for a closer analysis of the existence of some feeling of belonging to the cooperative.
The Belonging to a ‘‘System of Relationships’’ As we presented, two questions in the survey deal with workers’ opinion on asset locks and on what, according to them, should be done with the firm’s yearly profits (see Tables 2 and 3). Using these two answers, we have constructed a dummy variable that aims to capture those who have answered in favour of asset locks both in the first and in the second, in order to have an indicator of the ‘‘collectivist type’’ of worker.16 The outcome is that 40% of respondents have been defined as ‘‘collectivist.’’ Does this ‘‘type’’ of worker exhibit specific characteristics? The intention is to work out what the factors are that favour a positive attitude toward collective accumulation. First of all, there is a difference where the perception of outside options is concerned. While in the noncollectivist type the dominant answer to the question ‘‘if you were asked to, would you move to a capitalistic enterprise?’’ is ‘‘only if I were offered a higher wage’’ (53%), the collectivist type displays a higher subjective loyalty to the firm (this option is chosen by 39.6% of respondents), and a higher frequency of the answer ‘‘no, in any case’’ (among ‘‘non-collectivist’’ this was the answer of 23.7% of the sample, that rises to 39% among ‘‘collectivist’’ workers). Another interesting issue is how they look upon their relationship with the firm. The ‘‘collectivist’s’’ answer displays a remarkable decrease in the frequency of the answer ‘‘a normal working relationship’’ with respect to ‘‘noncollectivist’s’’ (from 47.6% to 29.3%), and an increase in the frequency of the answers ‘‘a contribution to the creation of better working conditions’’
217
Profit Reinvestment in Asset Locks: Workers’ Motivations
(from 4.9% to 13.4%) and a ‘‘system of relationships that goes beyond the job’’ (from 20.3% to 32.9%). Some differences are also shown regarding what the priority of the cooperative should be. Although job stability is the most frequent answer in both groups (about half of both subsamples), the ‘‘collectivist’’ group seems to give more importance to the quality of working conditions: the answer ‘‘the priority of the cooperative shall be the provision for better working conditions than elsewhere’’ was chosen by 27.6% of the ‘‘noncollectivist’’ and by 41.2% of the ‘‘collectivist’’ workers. Therefore, the importance given to the on-the-job consumption and to the relational aspects of work, seems to increase in the group that is in favour of indivisible accumulation. Before turning to the determinants of the ‘‘collectivist’’ attitude, we intend to go through the definition of some other related variables, starting with a variable that captures whether the cooperative matches workers’ expectations: do workers react by ‘‘punishing’’ or ‘‘rewarding’’ the firm if it does or does not match their expectations? The idea is to see whether workers display a strategic interaction with the cooperative or if they choose profit destination ‘‘unconditionally.’’ As a measure for matching workers’ expectations and firm’s behaviour, we have used two questions, where respondents are asked first of all what the cooperative’s main concern shall be and secondly what the priority actually is (see Table 5).17
Table 5.

First of all, we have to notice a ‘‘public good’’ preference of the interviewees: around 80% declare that job stability or the quality of working conditions are their priorities. We consider ‘‘disappointed’’ those respondents who choose one of these two and found that the aim of the cooperative was not so: they are 18.8% of the sample. We consider a positive opinion on reinvestment of profits into asset locks as rewarding for the firm (both as a sign of trust and as sign of what we defined a ‘‘collectivist’’ attitude), whereas we consider the opposite to represent a ‘‘punishing’’ attitude. As we can see in Table 6, the ‘‘disappointed’’ do not have a more hostile attitude toward asset locks; we can even see that greater importance is given to them as an instrument for a firm’s solidity, and that there is lower frequency of the opinion that they are just a tool so that board members do not share firm’s revenues. Albeit knowing the limitations of our proxies, we can argue that, even if worker members choose to reinvest profits as they expect some benefits from this choice, this does not seem to strictly depend on the fact that a set of expectations are achieved. This evidence is geared toward limiting the weight of strategic reasoning in individual choices and allows for the introduction of some elements of ‘‘normative expectations,’’ as discussed in the previous section. Last of all, we try and figure out a way to measure the feeling of belonging to the cooperative; we find it in the question where the workers were asked to define their relationship with the cooperative (Table 7). Although 40% of the respondents do not identify any difference between their relationship with the cooperative and a normal job, we consider that the second, third, and fifth answers indicate a feeling of belonging to the cooperative, that includes the relational aspect and the idea of a common aim. Following this, we constructed a dummy variable indicating whether

the worker gives a ‘‘team’’ meaning to its job relationship: 54.22% of respondents display a so-defined feeling of belonging to the cooperative.18 The types of workers identified by this variable show significant differences in their opinion on asset locks. As may be seen in Table 8, both the consideration of them as ‘‘fair’’ and as ‘‘necessary’’ increase among this type of workers. Moreover, there is a sharp decrease in the option chosen by those who think that asset locks are nothing but a tool for board members to keep revenues inside the firm; this can be a sign of greater trust in the cooperative and in its governing body. Also the opinion about how profits should be allocated displays a different pattern if the respondent reveals a feeling of belonging: among ‘‘belonging’’ respondents, there is a sharp decline in the frequency of those who think that profits should be shared out to members in any case. Those
220
CECILIA NAVARRA
who prefer accumulation for insurance reasons is higher. This may indicate that the concern for a firm’s stability and the importance given to employment protection are interlinked with the feeling of belonging and they influence the opinion on collective accumulation. The ‘‘team thinking’’ aspect can in fact be both cause and effect of the attempt to defend better working conditions and greater employment stability. This is the main conclusion that can be achieved by running a regression in order to look for the determinants of the ‘‘collectivist’’ type. We use a PROBIT model with the dummy ‘‘collectivist’’ as a dependent variable (Table 9, column a). Both the share of profits reinvested into asset locks and the per capita cumulated amount of locked assets of the cooperative display a positive effect regarding the probability that a worker will have a positive opinion on them. This result is interesting as it can show the feedback effect of the collective choice on members’ opinion. The fact itself of working in a cooperative where asset locks play an important role shapes the preferences of workers, in favour of a profit reinvestment policy.19 The dummy variable indicating the feeling of belonging has a strongly significant positive effect: this confirms the previous evidence and displays a high correlation between the positive opinion on reserve indivisibility and the importance of the relational component on the job. We find also evidence of a positive effect of the variable that indicates whether the respondent feels protected both from employment and wage fluctuations (‘‘insured’’); this may confirm the aforementioned interplay between ‘‘collectivist’’ attitude, feeling of belonging and job security. The size of the cooperative has a negative effect on the probability that the worker has a collectivist attitude, both if measured by the number of workers and as the amount of share capital: this can be interpreted as a – broadly speaking – collective action problem. The relationship between individual involvement and the firm’s policy is weaker in bigger cooperatives. It can be also a consequence of a greater degree of managerialization, that the decision regarding the allocation of profits is taken by a smaller group of people with respect to the size of the entire workforce. The variable indicating whether the worker is ‘‘disappointed’’ with respect to the aims of the cooperative does not display an effect that is significantly different from zero, consistently with what has been said beforehand. The negative coefficient of the dummy variable that indicates whether the respondent is a member and not simply an employee is worth looking at: a

disentangled by membership status: only 7.8% of employees thinks that profits should be shared out to members, whereas among members the proportion is 21.9%; 33.8% of employees think that profits should be kept within the firm as it is fair (‘‘it belongs to everyone and it is not individual wealth’’), while among members this proportion is less than 10%. On the contrary, the opinion on asset locks is quite similar among members and nonmember employees. If we split the observations among members and employees and perform the same regression as we did previously in order to look for the determinants regarding the probability that a worker will be ‘‘collectivist,’’ we see that the subsample of members almost reflects the results obtained on whole sample. On the contrary, among non members, the explanatory variables that were significant among members cease to be so: the positive feedback between a favourable attitude toward collective accumulation, the feeling of belonging to the cooperative and the employment protection it guarantees, only seem to work for worker members. An important point that can be highlighted only among members is the role of participation at the end-of-the-year decision on profit allocation20: the fact of participating in the decision makes the worker-member more willing to reinvest profits into asset locks.
CONCLUDING REMARKS The aim of this chapter is to investigate a peculiar feature of Italian worker cooperatives, the high propensity to reinvest profits into asset locks, that is a common fund nondivisible and nonappropriable by individual members. In the literature, we have found some arguments that explain its possible functions. Here, we intend to interpret it as a common pool resource and therefore to use the tools provided by the literature on collective action in order to get a different insight into the issue. Our question is what influences workers’ motivations in order to enhance their willingness to reinvest profits in the common fund. In the literature, we have found two main arguments to explain how the suboptimal free rider equilibrium may be avoided, by enhancing cooperation when contributing to a common good: repeated interaction among members and assumptions on rationality other than instrumental ones (namely ‘‘collective rationality’’). By means of a survey among a sample of workers of cooperatives affiliated to the Legacoop in the province of Ravenna (Italy), we have investigated to what extent these arguments are relevant to understanding the attitude of workers toward asset locks.
Profit Reinvestment in Asset Locks: Workers’ Motivations
223
First of all, we have evaluated the weight of the ‘‘time horizon’’ argument, that is the long-term relationship which workers set up within the cooperative. Time horizon is measured both in an individual and in an intergenerational perspective: if there is evidence that a large number of people tend to think that they will stay in the cooperative for their whole working life, not many of them expect their children to work in the same firm as they do. The relationship between the time projection within the firm and the opinion on asset locks and profit destination is not unambiguous. Concerning the effect of the accumulation policy of the cooperative on members’ permanence in it, we find some evidence of stronger loyalty to firms that accumulate a greater share of profits into asset locks, but we cannot disentangle whether it is due to the creation of a repeated interaction mechanism, or it is more likely due to the employment insurance that may be provided by the cooperative by means of asset locks accumulation. If we look at the incidence of the ‘‘time horizon’’ on the choice of profit destination, we find the expected effect (longer time horizon associated to a greater interest in the solidity of the firm) when workers are asked what they think about profit destination. If they are asked about indivisibility of the cooperative’s assets, the relationship is non monotonic, as many respondents who have a short-time perspective are concerned with their firm’s solidity likewise those who think they will stay in the cooperative for more time. Secondly, what we find is an increasing concern for ‘‘fairness’’ (asset locks as a ‘‘fair’’ allocation of the gain obtained by the collective effort) among those who have an intergenerational projection, both ‘‘forward-looking’’ and ‘‘backward-looking.’’ These last two observations tell us that there is room for assuming a positive role of ‘‘collective rationality,’’ as we do in the second part of the chapter. We then investigate the self-recognition by members as a part of a common project: this aims to go beyond the idea that people act following merely instrumental rationality, and to consider that people may ‘‘rationally’’ act as part of a collective agent. We have shown that workers identified as ‘‘collectivists’’ (those having a positive attitude toward asset locks) display some peculiar characteristics, namely a preference for the relational aspects of the job and for ‘‘on-the-job’’ consumption. We have then analyzed what the determinants of this attitude are. The main finding is a positive effect of the variable capturing worker’s feeling of belonging to the cooperative: our hypothesis of a role played by ‘‘collective rationality’’ seems to be confirmed. Secondly, we find a positive effect of the variable
224
CECILIA NAVARRA
indicating whether the worker feels insured with respect to employment and wage fluctuations: we argue that a positive relation exists among teamthinking, a positive attitude toward asset locks, and the role of the cooperative in protecting employment. We have not found any ‘‘punishing’’ strategies from workers who are disappointed with the satisfaction of the firm’s purposes, that shows workers’ nonstrictly conditional behaviour toward the cooperative. Interestingly, members who participate in the decision on profit allocation are more willing to reinvest profits: this can be an indication for board members, that may induce them to favour participation at members’ assemblies, if they aim to obtain a more favourable attitude to asset locks. Some difference can be found among worker members and employees: evidence tells us that the latter are on average more favourable to asset locks rather than the former. This can be explained by the fact that only members participate in profit sharing. If we split the observations in the two subgroups, we find that the positive interplay between the ‘‘collectivist’’ attitude and feeling of belonging disappears among those employees that are not members of the cooperative. We have learned through this case study that both the time perspective of workers in the cooperative and their feeling of belonging play a role in shaping preferences on profit destination. At a first glance, we find a positive correlation between a longer time horizon and a greater concern for profit reinvestment, that is the expected effect. Looking closer at the data, we nevertheless see a more complex relationship as two other aspects come into the game: the employment insurance role of worker cooperatives, and the ‘‘feeling of belonging’’ that links workers to the firm. This is clear if we look at the positive relationship between the intergenerational projection in the cooperative and the concern for fairness when supporting the nonappropriability of the firm’s assets. On the contrary, the positive effect of ‘‘team thinking’’ on the willingness to reinvest into locked assets is very strong, although it only appears among worker-members. The motivations among nonmembers seem to be different given that their opportunity cost of profit reinvestment into asset locks is lower. More may be done to discuss profit destination in worker cooperatives and the underlying mechanisms. We have tried to apply some reasoning in this work that may appear far from the literature on cooperatives: the results are geared toward taking into greater account the ties between the worker and the firm that are different to the simple job relationship.

225
Moreover, the effect of these ties seems to become greater as workers’ involvement in decision making increases.
NOTES 1. Law 142/2001concerning worker members in cooperatives. 2. Company Law Reform. 3. These are some members that only have a financial stake in the firm and own assets that are designed to help the cooperatives to find capital as a substitute to the stock market. We have evidence that these tools are underutilized in Italian worker cooperatives (Bonfante, 2008; Zevi, 2005), or are used to keep retired members in the cooperative (from qualitative interview to board members in the present case study). 4. The legal reserve, that is 30% of yearly profits. 5. Since 1977, revenues accumulated into asset locks were completely absolved of corporate tax, up to 2002, when a reform reduced the tax-free share of profits allocated in such fund to about 53%. In 2004, this decrease was mitigated, but the law stated that 30% of cooperative profits would be taxed anyway regardless of its destination. If the reason for indivisible accumulation were the reduction in taxes, we would thus expect a consequent reduction in the share of reinvested profits. 6. The ‘‘horizon problem’’ is a well-known argument that claims the inefficiency of the cooperative enterprise, as it foresees constant underinvestment by workermembers. Following this argument, workers lack incentives to invest in the firm because they have a truncated time horizon, that is their employment perspective in the firm: they therefore appraise investments with respect to their employment in the cooperative, that means that they maximise near term net cash flows, while they will not undertake those project whose payoffs occur far in the future. 7. The lower permanence is shown in the service sector (7.8 years), where there are the youngest cooperatives; if they are not so young, such as in the cleaning services, they are more likely to have a higher turnover. The longest permanence is in the agricultural sector (18.9 years), followed by the construction one (15.8 years): these are the sectors where coop have historically played the role of ensuring life-long employment. 8. In this respect, the above-average sectors are construction, manufacturing, and porters; agriculture displays that 55% of respondents have a fixed-term contract, but generally speaking this is due to the fact that they are used in applying this type of contract and to iterate it for a de facto nonfixed term relationship (source: author’s interview to board members). The sector that displays a more varied spectrum of typologies (19% fixed-term contracts and 14% collaboration agreements). 9. The picture varies depending on the sector: agriculture has the highest share (54%). This is confirmed by interviews with board members, even though they declare that this tendency is declining among new members. 10. We consider the respondent to ‘‘expect that his children will work in the same coop’’ if he answers that his children are already working at the same firm as he is, if he thinks that it is likely to happen, and if he would simply like it to happen. The
226
CECILIA NAVARRA
reason for including the last category is that we want to identify those workers that subjectively have an intergenerational perspective and how this influences their behaviour within the firm. 11. The same data disentangled by sector provides a different picture to the ‘‘backward-looking’’ intergenerational link: the decline is greater in agriculture and among porters, whereas as far as the construction sector is concerned almost the same proportion of people who had a relative working in the coop before him declared they expected their children to work there; last of all an increase can be seen in the service sector. 12. Note that employees are on average younger (36 years compared to 44 members), more educated (almost 40% have a BA that only 9% have among members) and have a higher qualification on the job (41% among them are blue collar, while this percentage is 72% among members). 13. It happens quite often that workers enter the cooperative as employees and then opt out for membership: the advantage for the cooperative in having more members than simple employees is twofold. On one hand, every member raises capital in the cooperative and, on the other hand, cooperatives have a fiscal advantage as they are considered as‘‘a mutualita` prevalente’’, a category introduced in 2003 that identifies the cooperatives that mostly operate with members from those that do not. In the case of workers cooperatives, to enter into this category, at least half of the labour costs of the coop has to be ascribed to worker-members. 14. Source: author’s interview to board members. 15. To be more precise, in cooperatives with cumulated asset locks per capita that is greater than 40,000 euros. If we perform a PROBIT model with y ¼ the respondent has an ‘‘open’’ time horizon, we do not find a significant effect of the asset locks measures. As it is intuitive, the age of a respondent and the fact of being member positively affects his/her time horizon within the coop (Navarra, 2008). Moreover, the correlation disappears if we use an intergenerational time perspective indicator. 16. We want to identify those workers who are in favour of asset locks accumulation consistently throughout the questionnaire, since we have seen some possible incoherent answers in the two specific questions. 17. In both questions they have the same possible answers. 18. As for the collectivist type, the attitude toward outside options is different following the ‘‘feeling of belonging’’. Although for the ‘‘not-belonging’’ agents, the dominant answer is that they would move to a capitalistic firm if they were offered a higher wage for the ‘‘belonging type’’ this is no longer a clear preference for ‘‘the belonging type’’: if we compare ‘‘not-belonging’’ with ‘‘belonging’’ agents, this answer declines from 55.74% to 40.57%, whereas the frequency of those workers who say that they would never move to a capitalistic firm rises from 20.77% to 37.74%. 19. It may be argued that a reverse causality problem may be in progress: nevertheless, the number of the interviewees in the sample is too small to think of a causality that goes from the fact of being a ‘‘collectivist’’ to the final decision of the firm’s policy. 20. The obvious reason is that nonmembers do not take part in a firm’s decisions.

DOES TRAINING POLICY HELP TO ATTRACT, RETAIN, AND DEVELOP VALUABLE HUMAN RESOURCES? ANALYSIS FROM THE MONDRAGON CASE$ Imanol Basterretxea and Eneka Albizu ABSTRACT The aim of this chapter is to ascertain the degree to which a training policy developed through corporate training centers is recognized as a source of competitive advantage for attracting, developing, and retaining valuable staff. The fieldwork is based on a survey of Human Resource (HR) managers from 66 cooperatives of the Spanish Mondragon cooperative group. The empirical test carried out confirms that Mondragon’s training policy, backed up by its corporate training centers, is perceived by HR managers as a tool that provides advantages to attract, develop, and retain valuable human resources. The results also suggest that those advantages are more moderate than has been cited in classic literature on Mondragon. The results of this study can be helpful for the growing

The link between training policy and the perceived ability to attract and retain valuable employees showed in this case can also be helpful for other companies that, as Mondragon, face limitations in wage policy. This chapter contributes to the literature on the educational fabric of Mondragon adding updated empirical evidence and incorporating the point of view of HR managers of the group’s cooperatives. With respect to the contribution of this chapter to the literature on training policy, the chapter’s findings, in particular those regarding the effect of training on worker attraction and retention, add empirical evidence to the few studies on the subject.

INTRODUCTION In a business environment in which people, with their knowledge, skills, experience, and motivation, are counted as a resource with great potential for generating sustainable competitive advantages, the war for talent acquires an increasingly sharper profile. Among the different HR policies designed within this competitive environment to attract, develop, and retain valuable staff, training policy has gained in prominence over recent years, with a growing number of companies choosing to bolster their internal training structures. As shown in Table 1, 15% of European companies with more than 10 employees that provide continuous training have their own training centers (Cedefop, 2010, p. 37). A comparison of the 1999 and 2005 figures shows that the percentage of companies with their own training centers increased in most European countries (Table 1). This percentage rises to 34% in the case of companies with more than 250 employees. To underline the bigger strategic role given to those corporate training centers, many of them have adopted the name of corporate universities.1 This growth in the number of companies that opt to create and reinforce corporate training centers, as well as the substantial economic resources devoted to this end, contrast with the scarcity of investigations designed to

clarify the degree to which these training centers can bring advantages to their companies in terms of attracting, developing, and keeping valuable staff. The present study concentrates on the case of one of the main Spanish business groups (Mondragon Cooperative Group) that has historically stood out for its firm commitment to the creation and consolidation of corporate training centers. The phenomenon of cooperative business development led by Mondragon, unmatched at a world level, has been receiving attention by researchers from different areas since the 1970s. The central question the research set out to answer was: what lies at the root of the success of this business group? According to several authors, there are different (though not mutually exclusive) reasons that explain the overall success of the experience. The people who make up this business group, cooperative members in the main, in combination with the corporation’s training policy, are understood by certain researchers to be one of the reasons for this cooperative business success (Agirre, 2001; Aranzadi, 2003; Asua, 1988; Bradley & Gelb, 1985; Campos, 2005; Chaves, 2003; Ellerman, 1984; Hoover, 1992; Meek and Woodworth, 1990; Morris, 1992; Thomas & Logan, 1982). Other reasons for success mentioned by the literature are also linked to corporate training policy: the existence of better managers and the development of in-group management tools (Albizu & Basterretxea, 1998; Basterretxea & Albizu, 2010a; Charterina, Albizu, & Landeta, 2007; Cheney, 1999; Clamp, 2000; Jacobsen, 2001; Logan, 1988; Smith, 2001; Thomas & Logan, 1982; Whyte & Whyte, 1988) and corporate cooperative culture (Aranzadi, 2003; Bradley & Gelb, 1985; Cheney, 1999; Smith, 2001). The objective of this research work is to ascertain the degree to which corporate training centers today act as a source of perceived competitive advantage for Mondragon. We feel this study might be of interest to HR managers and heads of training in companies and entities that, like
234
I. BASTERRETXEA AND E. ALBIZU
Mondragon, face constraints in their pay policy that stand in the way of competing through wages in the fight to attract and hold on to valuable staff. In addition, this investigation can throw some light on the debate around the creation of training structures by companies, constituting a new step forward in research on training policy as a source of competitive advantage. This chapter provides an update of the work previously carried out on the training structure of Mondragon. Most of the previous analyses (Asua, 1988; Bradley & Gelb, 1985; Meek & Woodworth, 1990; Whyte & Whyte, 1988) portray the educational fabric of Mondragon in the 1970s and 1980s. Therefore, they do not discuss several important strategic decisions related to the group’s training policy during the last two decades: most notably, the creation of Mondragon University (MU) and Otalora, the management training centre. Besides, this chapter differs from previous studies in the methodology used. While previous studies are mainly qualitative, based on opinions and data from a reduced number of managers of the corporate offices and some individual cooperatives, our survey offers conclusions based on a questionnaire completed by a representative sample of Mondragon HR managers. Regarding the structure of this chapter, an introduction to the research is followed by a review of works that analyze training policy as a stimulus to attract, develop, and retain valuable workers. The third part is devoted to a brief presentation of Mondragon and its training policy, followed in the fourth part by an explanation of the methodology employed in the investigation. Part five sets out the main results of the fieldwork. The sixth part is given over to discussion and also looks into the contributions that this investigation makes with regard to business practice. We finish the chapter by pointing out the limitations of the study.
THE VALUE OF TALENT The staff of a company, with their knowledge, skills, experience, and motivation, are regarded as one of the most powerful resources for generating sustainable competitive advantages (Bayo & Merino, 2000, 2001; Mueller, 1996; Wright, McManaman, & McWilliams, 1994), especially in high-performance organizations (Barron, 2008). This is especially true in the managerial and technical labor markets, where growing investments in technologies and high-standard machinery modify working methods and increase the need for a skilled workforce.
Does Training Policy Help to Attract, Retain, and Develop Human Resources?
235
Having valuable human resources, however, is no guarantee of obtaining competitive advantages unless such resources are scarce (Barney & Wright, 1998). The condition of scarcity stems from the heterogeneity of human resources. People differ in their abilities, knowledge, and attitudes and, consequently, in their contribution to the companies where they work (Wright et al., 1994). Within any labor pool, differences exist between individuals in terms of job-related skills and abilities (Barney & Wright, 1998), and it is hard to attract and keep people who guarantee highperformance levels in the organization. The war for talent is therefore a core concern for most firms. Effective strategies are nowadays being sought to achieve competitive advantages based on talent attraction and retention (Fegley, 2006). In addition, employees are adopting the philosophy that their job security lies in their employability, rather than in their employment. Talented workers with valuable skills expect employers to continually upgrade these skills, knowledge, and ability. Organizations that focus on developing talent will be in a stronger position to retain key employees (Boxall & Purcell, 2003; Capelli, 2008). Several recent investigations have dealt with the influence of training and development on a firm’s capacity to attract, retain, and develop valuable employees. Fey, Bjo¨rkman, and Pavlovskaya (2000), based on data from 101 foreign firms operating in Russia, find that providing non-technical training is positively associated with a higher degree of development, motivation, and retention of managers. A survey conducted by Hay Group (Hay, 2002) among 330 companies in 50 countries shows that lack of training and poor career development is resulting in employees leaving and moving on. In the same sense, the results of the research done by ExecEd and MSGM’s ISL on Australian managers (Hughes, 2009) suggest that management development and training programs are effective strategies for talent retention. Jean-Marie Hiltrop (1999) analyzes HR policies and practices of 115 multinational and 204 domestic companies located in Western Europe and the impact of such policies on their capability to attract and retain employees. With the help of an independent group of management consultants, he divides those companies into three groups depending on their ability (superior, average or poor) to attract and retain talented people, and then analyzes whether those differences can be explained by a different use of HR policies. According to his study, companies with a superior ability to attract and retain talented people scored well above those in the average and
236
I. BASTERRETXEA AND E. ALBIZU
low ability categories on several HRM factors. Out of eleven different factors, the training factor ranked second in importance when explaining the difference between companies with a superior ability to attract and retain valuable employees and those with an average or poor ability. Some other studies analyze the impact of training on employee retention not in isolation, but rather by linking the training policy with other HR policies and analyzing the link between the HR system and rotation. These studies (Batt, 2002; Gelade & Ivery, 2003; Guest, Michie, Conway, & Sheenan, 2003; Huselid, 1995; Krueger & Rouse, 1998; U´beda, 2005) also point to the existence of a positive relation between training policy and lower turnover.
THE MONDRAGON CORPORATION AND TRAINING POLICY The Mondragon corporation, whose origins date back to 1956, has now become a diversified business group with 85,066 employees,2 comprising over 260 companies, half of which are cooperatives, belonging to its industrial, finance, and distribution divisions. To facilitate the corporation’s development, Mondragon is backed up by a set of organizations, consisting of a multi-level network of training centers, 12 research centers, and suprastructure entities. It had a turnover of 13,819 million euros in 2009, exporting 3,172 million euros, 59.4% of the industrial group’s production value. It is present in 15 foreign countries in the shape of 75 productive plants and has its own branches in another nine countries. It is currently the seventh largest Spanish business group. As shown in Fig. 1, Mondragon is a highly diversified corporation. The Mondragon corporation has created several corporate governing bodies (Congress, General Assembly, Governing Council, Divisions, etc.), although it should be noted that each of the cooperatives in the group is a sovereign entity. Mondragon’s corporate governing bodies and central services cannot base their power on controlling the cooperatives’ assets or shares in the cooperatives’ capital, since each cooperative’s assets and capital belong to its members. Therefore, the corporation does not own the cooperatives; rather, it is the cooperative members themselves that ultimately vote whether to join or leave the Mondragon corporation. Membership in the corporation obliges cooperatives to fulfill several commitments, such as the relocation of members from other cooperatives in

crisis; a distribution of profits based on solidarity3 and reinvestment;4 the pooling of part of their returns;5 a uniformity in the initial capital contribution required from new members;6 and limitations on managers’ salaries. The salary limitations of managers in Mondragon cooperatives have always been an important source of internal controversy and external debate at Mondragon (Basterretxea, 2008; Basterretxea & Albizu, 2010a; Kasmir, 1996; MacLeod, 1997; Morris, 1992; Thomas & Logan, 1982). In 2008, only 3% of cooperative members earned a salary higher than 3.5 times that of the lower paid member (Mondragon, 2009, p.52) and, in most cooperatives, the salary of the top manager is still limited to 4.5 times more than that of the lowest paid cooperative member (Basterretxea & Albizu, 2010a). Those limited wage differentials make it difficult to attract and retain managers and highly valuable professionals.

From its beginnings, the active training policy of the Mondragon group has constituted one of its most distinctive characteristics. As Arizmendiarrieta, founder of the Mondragon project, put it (Ormaetxea, 1991, p. 44), ‘‘it has been said that cooperativism is an economic movement that uses educational action, while the definition could also be altered to affirm that it is an educational movement that uses economic action’’. Most analyses that set out to explain the successful evolution of the Mondragon Cooperative Experience ascribe a relevant role to the educational centers of the corporation as a group. This appraisal of corporate training centers as a source of competitive advantage or as a basic explanatory component in the Mondragon success is cited both in the analyses made by the group’s founders and successive top managers in different internal publications of the corporation, and in a good number of studies carried out by researchers from outside the Mondragon experience in the 1980s and 1990s (Asua, 1988; Basterretxea & Albizu, 2010a; Campos, 2005; Ellerman, 1984; Meek & Woodworth, 1990; Morris, 1992; Thomas & Logan, 1982; Whyte & Whyte, 1988). The Mondragon Corporation has created a complex network of educational centers that comprises a university, various vocational training centers, a business school, a cooperative and management training centre, and even children education centers at primary and secondary levels. This network is complemented by a set of associated companies and entities, which pursue objectives such as the promotion of entrepreneurship, dual training, language teaching, or company-applied research. Table 2 attempts to synthesize Mondragon’s complex educational framework. Among the various corporate training centers, a special role is played by Mondragon Unibertsitatea (MU/Mondragon University). This university, officially set up in 1997, is supported by three educational cooperatives with a long track record: over 50 years of experience within the areas of university qualifications (in Engineering, Business and Humanities) and of Vocational Training (industrial branches). In the educational year 2007/ 2008, MU had 3,707 pupils signed up for university qualifications, 10% of whom were studying at third cycle and postgraduate level. Its offer takes in 10 high-level training studies, 24 university degree courses, 21 university postgraduate courses, and 5 third-cycle studies (PhD). In addition, there is a wide offer in continuous training, most of which is made up of short courses generated by demand from companies in the same milieu, mostly group cooperatives. The faculties that constitute MU today were home to the first cooperative members within the Mondragon Experience and were the historical

suppliers of technicians, engineers, holders of diplomas and degrees in Business Administration, entrepreneurs, and managers for its cooperatives. MU students have an opportunity to combine their studies with work in the industrial cooperative Alecop, a cooperative within the Mondragon Group created in 1966, whose workforce has, since its foundation, been principally made up of students from the different centers that today form MU. Thus, more than 7,500 students have combined their studies with part-time work in this cooperative or in other Mondragon cooperatives to which Alecop assigns some of its student-workers. The bodies for management, shareholding, ownership and payment systems are practically the same in Alecop as in the remaining Group cooperatives, which means that the cooperative-based work experience of MU students at Alecop lubricates socialization in cooperative values and the future integration of technicians and university graduates in the Mondragon cooperatives (Asua, 1988; Meek & Woodworth, 1990; Thomas & Logan, 1982; Whyte & Whyte, 1988). In addition to the university, the Mondragon Group runs specialized vocational training centers (Eskola-MU-, Lea Artibai, Txori Herri) in industrial areas where local cooperatives are operative (approximately 1,000 students enrolled in formal vocational training and 5,691 people in continuous vocational training in those centers during the educational year 2007/2008). Another corporate training center that is of great importance for the cooperative group is Otalora, the Cooperative and Management Training Center of Mondragon, founded in 1984 for the purpose of training

managers and members of social bodies attached to the Mondragon cooperative group. Otalora is the training center most closely linked to the specific needs of the Mondragon cooperatives and does not offer any training to people outside the group. It offers a breadth of training designed to facilitate the internal promotion process, improve the competences of company managers, benchmarking and the dissemination of cooperative culture and values among managers and members of the control bodies. Prominent within this training offer is the MBA Executive in Cooperative Company Management. More than 500 executives and managers from Mondragon cooperatives have taken Otalora’s MBA, and practically all the current executives in the Group’s cooperatives have taken this Master course. In the educational year 2007/2008, Otalora offered Management Training involving 738 people and Cooperative Development training with the attendance of 1,960 people. The Mondragon cooperatives aid in the funding of MU, Otalora and the Group’s vocational training centers. By law, Spanish cooperatives must earmark 10% of their profits to the Fund for Cooperative Education and Promotion, and Mondragon cooperatives allocate a considerable portion of those funds to the corporate training centers.7 These contributions from cooperatives are the main source of funding for Otalora, the management training center. Vocational training centers are mostly funded by Public Administration, and in the case of MU, it is the students themselves that cover most of its expenses. Besides contributing to the funding of the training centers, the group’s cooperatives play an active role in the bodies that manage and control the centers. The cooperatives that collaborate with corporate training centers have a third of the votes in the General Council and in the training centers’ Council. This allows the training content to suit the needs of the cooperatives (Basterretxea, 2008). In any case, the training offered in MU and in the corporate vocational training centers is not specific to the Mondragon cooperatives and is also valuable for work in firms outside the corporation.8 Mondragon’s commitment to training is reflected in the training structures that the corporation has created, as well as in the changes in the cooperative members’ qualifications. As shown in Table 3, which compares the Industrial Group’s training levels in 1987 and 2006, the change has been remarkable. In this period, the group has grown from a workforce that was mainly unskilled or had only basic qualifications to one in which most employees are at least high school graduates or have a vocational training degree.

This increase in qualifications among members is mainly explained by the fact that a growing number of cooperatives have set a minimum of a vocational training degree as an admission requirement, which has allowed the percentage of vocational training graduates to double in the reference period. The percentage of members with high school qualifications and those with university degrees has more than doubled in that same period. The continuous training offered by the corporation has also contributed to that higher degree of qualifications. In the early 1990s, over 1,000 unqualified members earned vocational training degrees through the professional retraining plan implemented by Mondragon to facilitate the workforce’s multi-skill capability and the relocation of members among cooperatives in times of crisis (Basterretxea & Albizu, 2010b).
METHODOLOGY OF THE INVESTIGATION The survey was carried out with the enterprises in the group. More specifically, the population under study comprises all the cooperatives that were part of the Mondragon Group in the Basque Country and in Navarre (Spain) in December 2006, with the exception of corporate training centers and cover entities (companies created to provide services to cooperatives in the group). Also excluded were companies that have become members of the corporation over the past five years and had no previous link with the corporate training centers. Accordingly, the population was made up of a total of 81 firstdegree cooperative companies (cooperative parent companies), 66 of which collaborated with the research by replying to the survey, that is to say, 81.5% of the population.

The questionnaires, with an accompanying letter, were sent to HR managers in Mondragon, following a pre-test with various cooperative managers. In the cooperatives where this position did not exist, the questionnaire was sent to the company executive manager. Subsequently, the same standardized questionnaire acted as the basis for telephone interviews with the people who had initially been contacted by post. These telephone interviews were carried out between November 28, 2006, and January 11, 2007. The HR managers’ responses were measured using five-point subjective scales ranging from 1 (totally disagree) to 5 (totally agree). The respondents were asked to evaluate their perceptions about the link between Mondragon’s training policy and the ability of its cooperatives to attract, develop, and retain valuable employees. Many of those subjective perceptions are relative perceptual measures,9 obtained by asking the respondents to evaluate their ability to attract, develop, and retain employees (via training policy), in comparison with the ability of their competitors (e.g., ‘‘The continuous training we have provided has enabled us to develop more valuable staff than the staff of our competitors’’). Appendix A details the variables, evidence, and measures of relative perception of the questionnaire used in the chapter. Furthermore, we have also taken into account a series of classification variables to find out whether cooperatives that collaborate to a greater degree with Mondragon’s corporate training centers and those that put more effort into continuous training perceive greater competitive advantages (Appendix B).
RESULTS Mondragon cooperatives have a preference for collaboration with corporate training centers and particularly with MU.10 40 of the 66 cooperatives surveyed cite MU as the university they mainly collaborate with. A significant percentage of vocational training graduates and university graduates who work in cooperatives (around 38% in both cases) come from corporate training centers, although the distribution of these centers is not uniform if we take into consideration the sectors that the companies belong to, the groups they fall into, and their location. The Mondragon cooperative collective is not homogeneous where the relation with corporate training centers and preferential recruitment from their graduates is concerned. The cooperatives that are geographically closest to the centers and those that belong to the industrial group exhibit

the highest rates of collaboration with corporate training centers and are the most inclined to resort to them when obtaining staff. The remaining cooperatives, particularly those in the retail group, scarcely collaborate with the corporate training centers, and their intake of graduates from them is lower. All told, a fourth of the cooperative managers, all of them in cooperatives in the industrial group, come from corporate training centers. The answers to the questions that measure the effort in continuous vocational training in the cooperatives (VC5 to VC8 in Appendix B) show a major commitment to training. Comparing our results with those of the Continuing Vocational Training Survey coordinated by Eurostat in 2005 and presented in 2008,11 we find that Mondragon cooperatives put considerably more effort into the continuous training of their employees than Spanish and European firms of a similar size. In 2006, investment in continuous training in Mondragon cooperatives represented an average of 2.87% of the total wage bill.12 This 2.87% on training outlay as a percentage of labor costs more than doubles the average for Spanish companies, which is situated at 1.2%; it significantly surpasses the 1.6% average for companies in the EU-27, and it lies among the average percentages for the companies in the European countries that are most committed to continuous training. This higher training input is also reflected in a higher proportion of employees who benefit from training (50.5% against 33% in the EU-27) and in more hours of training per employee (23.74 hours, against the average of 12 for the EU-27). The greatest differences in training input between the Mondragon cooperatives and Spanish and European companies are found in the segment of small and medium businesses, which includes 65% of the cooperatives in our sample. Only 23% of the continuous training of cooperative workers takes place in corporate training centers. When the recipients of continuous training are cooperative managers, the training is based to a greater degree in corporate training centers. In fact, 36% of management training takes place in corporate training centers (Basterretxea, 2008, p. 497). Those differences are coherent with the different kind of training provided to workers and managers. Much of the training provided to blue collar cooperative members is generic, to foster the multi-skill capability of workers and their relocation among different cooperatives in case of crisis (Basterretxea & Albizu, 2010b). On the contrary, much of the management training, especially that provided at Otalora, is more specific to the Mondragon cooperatives. This specific training supports the retention of managers, to the extent that such training has more value in Mondragon or in other cooperatives than in other local capitalist firms (Basterretxea & Albizu, 2010a, p. 11).

Advantages for Attracting Valuable Staff To test out if Mondragon’s training policy, backed up by its corporate training centers, helps cooperatives to attract valuable staff, questions were formulated covering seven dimensions. The aggregate results of the responses given by HR managers are shown in Fig. 2. 76.6% of HR managers agree that cooperative training centers produce staff who is more familiar with cooperative culture, while 12% are indifferent and only 10.9% disagree. The data analyzed, therefore, allow us to affirm that the group’s training centers fulfill a socializing function of cooperative values among students. These values constitute one of the relevant factors that have provided the Mondragon Experience with continuity and cohesion. In any case, it should be noted that the HR managers’ assessment regarding this question is slightly less positive among those cooperatives with a higher percentage of graduates from corporate training centers, as shown in Table 4. Likewise, Mondragon HR managers consider that candidates from corporate training centers have a more favorable attitude toward joining a cooperative enterprise as workers (53.1% in agreement and 17.2% very much in agreement). Mondragon cooperatives surpass the barriers to the attraction of valuable staff that are common to Social Economy enterprises. 46.8% of HR heads are in agreement or totally in agreement that their ability to attract valuable employees is greater than their competitors; 40.3% express no preference,

which may be interpreted as a situation of competitive parity, and only 12.9% find themselves in a situation of competitive disadvantage. When asked directly whether their relation with training centers is conducive to obtaining competitive advantages for attracting graduates, more than half of the HR managers surveyed answered affirmatively. The awareness of competitive advantages deriving from the relation with training centers is significantly greater in the collective of industrial cooperatives (3.62 of 5 against 2.1 for other cooperatives) and in those that mentioned a corporate training centre as the centre they prefer to collaborate with (3.65 against 2.96 for cooperatives that collaborate with other training centers).13 The advantages deriving from technical training that is more suited to the needs of companies are not so visible for the cooperatives surveyed taken as a whole, although they are perceived by a significant percentage of HR heads. 38.7% are of the opinion that their corporate training centers produce candidates with competences and knowledge that are more in tune

with their needs, against 17.7% who consider the opposite and 43.5% who express no preference. The assessment is better in the case of cooperatives that mentioned MU as the university they collaborate with first and foremost (3.34 of 5, against 2.92 of cooperatives that collaborate with other universities).14 When asked whether the employment services of corporate training centers facilitate the cooperatives’ recruitment and selection processes, opinion is divided among the companies surveyed (46% unfavorable, including 19% absolutely unfavorable, against 42% completely favorable). The assessment is significantly better in cooperatives that collaborate first and foremost with corporate training centers (3.28 of 5, against 2.17 for the cooperatives that collaborate with other training centers), in industrial cooperatives (3.04 of 5 against 1.56 for other cooperatives)15 and in cooperatives with a higher percentage of graduates in vocational training from corporate training centers (Table 4). When asked whether the corporate training center’s employment services contribute to a reduction in the number of unsuccessful staff selections, the response is negative for 57% of the HR managers surveyed. Despite this globally negative assessment, the evaluation is again significantly better in cooperatives that collaborate first and foremost with corporate training centers16 and in those that belong to the Industrial Group.17
Advantages for Retaining Valuable Staff Fig. 3 shows the average values of the responses Mondragon HR managers gave to questions designed to evaluate whether the group’s training policy and corporate training centers help cooperatives to retain valuable staff. Almost 70% of Mondragon cooperatives can rely on competitive advantages for the retention of valuable staff when compared with companies in the same competitive environment, while another 17.7% find themselves in a situation of competitive parity. This advantage vis-a`-vis the retention of valuable staff that can be appreciated in this work confirms that Mondragon has been able to overcome the barriers hindering staff retention that have been pointed out in Social Economy literature. Regarding the degree to which training policy based on corporate training centers helps in the securing of this competitive advantage for retaining valuable staff, we find conflicting evidence. Lower rates of turnover of valuable staff are correlated with various indicators for training policy based on corporate training centers (Table 4).

Thus, cooperatives with a higher percentage of professionals from corporate vocational training centers exhibit lower rates of relative turnover than the rest of the cooperatives. This correlation is positive and significant at 5%. The ability to hold on to valuable staff is also greater the higher the proportion of graduates there are from MU. This correlation is positive and significant at 1%. There are also differences between the cooperatives that have mentioned MU as the university they mostly work with, and all the rest. In the former, the perception of advantages for retaining valuable staff is greater. Similarly, 62.5% of Mondragon HR managers consider that their cooperative provides more continuous training than their competitors and that this commitment to training facilitates the retention of valuable staff. The perception of competitive advantages for retaining valuable staff is also linked to different indicators of effort put into continuous training by cooperatives. The greater the percentage of employees who have received continuous training over the previous year, and the more hours are devoted to training per employee, the greater the perception of HR managers that they possess advantages for retaining their professionals. These perceived advantages, though, are not correlated with economic investment on continuous training, measured as a percentage of the wage bill that such investment represents (Table 5). The consideration of continuous training as a factor that reduces the turnover of valuable staff in cooperatives is not determined by such training being given in corporate training centers. In fact, we have not detected a significant correlation between the perception of advantages for retaining valuable staff and the percentage of continuous training provided in collaboration with Mondragon’s corporate training centers.

In contradiction with the results that indicate a positive relation between training policy based on corporate training centers and securing advantages for the retention of valuable staff, less than a third (32%) of HR managers surveyed considered that professionals from corporate training centers are more loyal to cooperatives, while the majority expressed no preference with regard to this statement (43.4%). It must be stressed that there are no significant differences in this assessment in terms of whether the cooperative collaborates to a greater or lesser degree with the Mondragon training centers, or whether it has a greater or lesser intake of their graduates.
Developing Valuable Staff The averages of the replies to the questions asked to assess whether Mondragon’s training policy and training centers help cooperatives to develop valuable staff are reflected in Fig. 4. Continuous training has had a positive effect on the motivation of workers, according to 74.6% of Mondragon heads of HR. For a vast majority (76.2%) of Mondragon HR managers, continuous training has led to better quality in the products and services of their companies. Most of their cooperatives have adopted quality strategies, with a great deal of effort and notable success. What emerges from the results of this survey is that the cooperatives’ training policy has been in alignment with the quality strategy, and has had a positive influence on it.

cooperatives that provide training for a greater proportion of employees are the ones that more positively evaluate the effect of training on quality (Table 5). This highly significant positive correlation is because the management model and the total quality systems implemented by the Mondragon cooperatives require the active participation of the greatest possible number of employees in continuous improvement. When the managers were asked whether Mondragon’s corporate training centers are conducive to continuous training that is more suited to the needs of the group’s companies, more than two-thirds (67.7%) of the heads of HR at Mondragon were in agreement that this is so. This positive assessment of corporate training centers does not differ in terms of the degree to which the cooperatives collaborate with them in order to provide their employees and their managers with continuous training. As well as producing more motivated staff, more than half of those surveyed (54.2%) consider that continuous training has enabled their cooperatives to develop more valuable staff than their competitors. This perceived competitive advantage increases the higher the percentage of employees take part in continuous training actions (Table 5). A significant percentage, though not the majority, of the HR managers consulted consider continuous training to have had a positive effect on greater customer satisfaction. Specifically, 44.5% of those surveyed state that training has facilitated a more rapid response to customer requirements, and 39.3% that training has brought about a reduction in the number of such complaints. Once again, the factor that best explains why continuous training leads to better customer service is the fact that training is offered to a greater proportion of employees (Table 5). For 37.7% of the managers interviewed, continuous training has contributed to a reduction of costs. This cost decrease due to permanent training is particularly perceived in cooperatives that extend their continuous training program to a greater percentage of their employees, and in those that rely more on corporate training centers to cover their continuous training needs.
DISCUSSION The Mondragon cooperatives overcome the barriers against attracting valuable staff that are common to Social Economy enterprises and, in the main, evaluate their situation as one of parity or of competitive advantage in relation to companies in their sectors in terms of being able to attract valuable employees.
Does Training Policy Help to Attract, Retain, and Develop Human Resources?
251
Mondragon’s training policy, backed up by its corporate training centers, is internally seen as a source of competitive advantages for attracting valuable staff, fundamentally due to a supply of candidates who are more socialized in cooperative culture and more inclined to want to work in cooperatives. These perceived advantages generated by corporate training centers are confined to the cooperatives in the Industrial Group. Mondragon’s HR managers consider that continuous training policy produces more motivated and more valuable staff than is the case for competitors. They also consider that continuous training has led to improvements in quality and, to a lesser extent, a reduction in costs and better customer service. The perceived competitive advantages deriving from continuous training in the Mondragon cooperatives are positively correlated with the percentage of employees receiving such training. However, we have not found a correlation with other indicators of effort on continuous training, such as the number of hours of training per employee, or training budget in relation to wage costs. The Mondragon cooperatives evaluate their situation, in the main, as one of competitive advantage with regard to companies in their field when it comes to holding on to valuable staff. Such perceived competitive advantage is to a large extent explained by the formula of offering more continuous training provision than their competitors. It is not clear, however, that the training background of workers (cooperative vs. non-cooperative training centers) is directly related to the propensity of workers to move on to other employment. The link between the provision of training and retention can be explained, in the case of training provided to managers, by its high specificity. This specific training supports the retention of managers, to the extent that such training has more value in Mondragon cooperatives than in investor-owned firms. In the case of the training provided to blue collar cooperative members, training is more general than in investor-owned firms. This general training fosters the multi-skill capability of the workforce and makes it easier to relocate members in different jobs and cooperatives in times of crisis (Basterretxea & Albizu, 2010a, 2010b). Thus, general training provided to workers enhances job security. Since job security is the most valued factor by cooperative members in the employee satisfaction surveys carried out in Mondragon (Basterretxea, 2008), we can suggest that general training enhances employee retention when it generates a higher degree of employment security. The link between training and retention can also be explained by the internal promotion that follows many training processes. This is especially
252
I. BASTERRETXEA AND E. ALBIZU
true in the case of training provided to managers, since management training and promotion policies are regarded as inseparable policies in Mondragon. Another factor that can explain the retention of employees after training is the existence of exit barriers. Anyone seeking membership in a Mondragon cooperative is aware of the risk of losing part of the initial contribution to the cooperative’s share capital and the subsequent accumulated dividends if they leave the cooperative. A fraction of their initial capital contribution (up to 20%) goes straight into the cooperative’s reserve fund and is not refundable on an individual basis in any case. Besides, when members leave, the cooperative can deduct considerable sums from their initial contribution and from their account’s accumulated dividends, a deduction that will vary according to how much the cooperative invested in the member’s training (Gorron˜ogoitia, 1991; Larran˜aga, 1991). The time factor and asset mass efficiency constitute barriers against any imitation of the Mondragon corporate training centers. The combined effect of time compression diseconomies, experience economies and time flow trajectories make the time factor an important obstacle for any competitor wishing to create a corporate training centre structure or mechanisms for company-centre cooperation as efficient as those created by Mondragon over decades. A training policy based on corporate training centers, which provides Mondragon cooperative companies with so many perceived advantages, may also be a source of competitive disadvantages in the future because of the specificity of resources involved. The Mondragon network of corporate training centers (and the degrees and diplomas they provide) has its roots to a large extent in the historical needs of industrial cooperatives in the field of human resources. This specificity means that some cooperatives that are in a process of expansion, such as those in the Retail Group, have historically benefited little from the corporate training centers. Likewise, this specificity acts as a hindrance to the corporate training centers being able to provide assistance in launching and driving some of the new business lines that Mondragon aims to give impetus to in its present strategic reorientation. This calls into question some aspects of the training policy that has been pursued until now and suggests that the corporation should reconsider the keystones of its relation with the corporate training centers. This chapter contributes to the literature on the educational fabric of Mondragon adding updated empirical evidence to previous studies and incorporating the point of view of HR managers of the group’s cooperatives. Our results show that Mondragon HR managers consider that the corporate training policy and training centers generate many advantages, but we have

253
also found such advantages to be more moderate than those cited in the historical literature on Mondragon. The broader source of data and opinions of the present study shows a less homogeneous link between corporate training centers and cooperatives than in previous studies. Likewise, we have found that some sources of advantage according to previous literature (technical training more suited to the needs of cooperatives, training centers as facilitators of recruitment, lower rotation of graduates in corporate training centers) are not perceived by the cooperatives’ HR managers. With respect to the contribution of this chapter to the literature on training policy, the chapter’s findings show that training policy and corporate training centers can be conceived by HR managers as a source of advantages for the attraction, development, and retention of staff. Most studies on training policy analyze the impact of training on business results, but there are few studies that explore the link between training and employee attraction and retention. The chapter’s findings, in particular those regarding the effect of training on worker attraction and retention, add empirical evidence to the few studies on the subject. Besides, our results suggest that training policy can have a positive impact on employee attraction and retention in a context of serious limitations and particularities in other HR policies, such as wage policy. Other large business corporations that are presently thinking of making a commitment to strengthening their training structures or creating corporate training centers on the same lines as those analyzed in this work would have to take into account that such a move only makes sense in interconnection with other HR policies. In the experience that has been analyzed here, high investment in training takes on more meaning when internal job markets and extensive job ladders exist in each cooperative and in the corporation. Moreover, this is a corporation in which business culture is the main point of union between the cooperatives that form it, which demands extra input into corporate culture training. Another feature of this corporation’s HR policy is the existence of wage limitations, and such a restriction stands in the way of using pay as a preferential means of attracting and retaining valuable staff. In companies where business culture is not so important, where the possibilities of promotion are relatively slim, and where it is easy to attract and retain talent with competitive wages, it probably does not make sense to set up a corporate university and other training centers similar to those analyzed in this study. Finally, any possible imitator would have to be aware of the high cost that could be incurred by the creation of a training centre structure similar to
254
I. BASTERRETXEA AND E. ALBIZU
that of Mondragon. In the case we have studied here, this cost is, to a large extent, defrayed as a result of the favorable tax treatment that is accorded in Spain to investments by cooperatives on continuous training and on their corporate training centers. Consequently, even if a competitor were to develop continuous training programs and corporate training centers as valuable as those of Mondragon, the costs the competitor would have to incur would cancel out part or all of that value.
LIMITATIONS The main limitations of the study stem from the subjectivity of the data used (opinions of HR managers about the effectiveness of training policies). This subjectivity bias can be especially important in those questions in which HR managers evaluate training policies that they have themselves supported or implemented (continuous training policies in the main). In order to reduce this subjectivity, it would be interesting to conduct further research to learn what kind of answers to the same questions would be provided by workers. Another limitation is that we have not considered possible reverse causality relationships. In some questions in which most HR managers strongly disagreed with some factors as a source of advantages (e.g., when asked whether MU employment services facilitate their recruitment process), we have highlighted that those cooperatives with a higher degree of collaboration with corporate training centers had a more positive point of view. In those questions, there could also be reverse causality: the negative assessment of most of HR managers on some features of Mondragon training centers (e.g., their employment services) may explain a lower degree of collaboration with such centers.

3. 10% of profits are allocated to the Fund for Cooperative Education and Promotion. This fund promotes the training of members and workers, intercooperative relations, and cultural and social welfare programs. Cooperatives earmark 20% of this fund for the Fund for Inter-Cooperative Education and Promotion, which gives financial support to the corporate training centers. 4. 45% of profits are allocated to the cooperative’s Reserve Fund. The remaining 45% is capitalized into each member’s account. 5. Cooperatives must pool between 15% and 40% of their returns alongside the rest of cooperatives belonging to the same division (see the specialization areas in Fig. 1). In addition, they must earmark 10% of their returns for the Mondragon Investment Fund. 6. Historically, new members of Mondragon cooperatives have made an initial contribution to the share capital of no less than the equivalent to the annual salary of the lowest paid member. In 2008, this amounted to 14,000 euros. 7. For the allocation of funds in different years, see Basterretxea (2008). 8. According to the Basque Employment Service (Lanbide, 2004), nearly 40% of the engineers from Mondragon University entered a cooperative in 2000 and so did 27% of those who had completed Management studies. This means that most of the graduates entered a company that did not belong to the group. 9. While it is true that perceptual data may introduce limitations through increased measurement error and the potential for mono-method bias, the benefits outweigh the drawbacks (Fey et al., 2000). Furthermore, there is precedent for using such perceptual measures in similar research (e.g., Delaney & Huselid, 1996; Fey et al., 2000; Youndt, Snell, & Dean, 1996). Additionally, prior research has shown that subjective measures of firm performance are well correlated with objective measures (Geringer & Hebert, 1991; Powell, 1992). 10. See answers to the questions VC1 to VC4 in Appendix B. 11. See http://epp.eurostat.ec.europa.eu 12. If we consider Mondragon Corporation as a whole, and not only the cooperatives of the group, the percentage of training expenditure over total personnel costs was much lower this year (0.6%). This difference may be due to sample bias in our survey (only 40 HR managers of the cooperatives were able to quantify the percentage in the survey, while virtually everyone knew the percentage of employees who had been trained, or the number of training hours per employee). This divergence of figures may also be explained by a high concentration of training expenditure in the cooperatives of the group, while spending on training is much smaller in subsidiaries. 13.

APPENDIX A The variables included in the questionnaire are the following: V1 – ‘‘The capacity of my company to attract valuable employees is better than that of others in the sector.’’ V2 – ‘‘Corporate training centers produce candidates who are more familiar with cooperative culture.’’ V3 – ‘‘Corporate training centers produce candidates who are more willing to work in a cooperative.’’ V4 – ‘‘Corporate training centers produce candidates with knowledge and technical competences more suited to the needs of my company.’’ V5 – ‘‘The employment services of MU and other corporate centers facilitate our recruitment and selection process.’’ V6 – ‘‘The employment services of MU and other corporate centers allow us to reduce the number of unsuccessful selections.’’ V7 – ‘‘Our relation with training centers provides us with competitive advantages when attracting graduates.’’ V8 – ‘‘The turnover rates of valuable staff are lower than in companies within the same competitive environment.’’ V9 – ‘‘The turnover of professionals from corporate training centers is lower than that of those trained in centers outside of the Mondragon network.’’ V10 – ‘‘Offering more continuous training than competitors helps us to retain valuable staff.’’ To measure whether continuous training produces more valuable staff, in addition to the perceptions of HR managers, we included a series of indirect indicators that are usually applied in scientific literature evaluating the efficiency of company training activities. These indicators indirectly measure whether training produces more valuable staff, through the consumer’s value perceptions. Thus, continuous training produces more valuable staff, if the latter are able to produce better quality results, providing better customer service, or contributing to a reduction in costs. Therefore, the variables included to test this question are the following: V11 – ‘‘Having corporate training centers enables us to provide continuous training that is better suited to our needs.’’ V12 – ‘‘The continuous training we have provided has enabled us to develop more valuable staff than the staff of our competitors.’’ V13 – ‘‘Continuous training has provided our workers with greater motivation.’’

GOVERNANCE AND BEHAVIOR IN NONPROFITS: ANALYSIS OF URUGUAYAN HEALTH CARE ORGANIZATIONS Juan Jose Barrios and Mieke Meurs ABSTRACT Literature on nontraditional firms has focused on behavioral differences with for-profit firms. Less attention has been given to the variations in behavior among nontraditional firms. This chapter examines differences across three types of Uruguayan nonprofit health care organizations. This chapter draws on a unique dataset of Uruguayan health care organizations during the period 1982–1990, as well as interviews with doctors working in the three types of nonprofits during spring 2010. We use a simple OLS regression to identify differences in average behavior, and differences in reaction to a regulatory change. The chapter shows that structure of stake holding and governance significantly affect behavior, even where many behaviors are highly regulated. These findings highlight the importance of specifying governance structure when predicting behavior of nontraditional firms.

firms will be more meaningful if the governance structure of nontraditional firms is common and specified. A limitation of our study is our inability to control for the timing of degeneration of producer cooperatives. This would be one element of governance structure to consider in future data collection. These findings highlight the need to avoid drawing broad policy conclusions from the behavior of a specific subset of nontraditional firms. This chapter highlights the importance of carefully specifying stakeholder and governance structure when predicting behavior of nontraditional firms. It is of interest to anyone using a sample of nontraditional firms to test general hypotheses about their behavior.
INTRODUCTION Much of the literature on the behavior of nontraditional firms (nonprofits and cooperatives) has focused on predicted differences with traditional, forprofit firms. Less attention has been paid to variations in behavior among different types of nontraditional firms, resulting from the structure of stake holding or ways that stakeholders participate in governance. This omission may lead to unfounded conclusions about behavioral or performance differences between traditional and nontraditional firms. For example, in a 1992 study of the impact of property rights on efficiency, Fizel and Nunnikhoven use cross-sectional data to compare for-profit and nonprofit nursing homes without specifying nonprofit type. They conclude that for-profits are more efficient than nonprofits in general – relative performance is not linked to a particular form (or forms) of nonprofit. In a 1993 study, L.L. Peters performs a meta-analysis of performance of for- and nonprofit electric companies. Although he notes the importance of possible variation in performance by type of nonprofit, the nature of the previous work forces him to consider municipal and cooperative firms together as ‘‘nonprofits.’’ Peters finds no significant difference in performance between for- and nonprofit firms. In recent years, more attention has begun to be paid to the question of how nonprofit form affects behavior. Avner Ben-Ner and Benedetto Gui (2003) provide a careful typology of organization type, focusing on variation by residual claimancy and control, and discuss behavioral implications of the differences.

examine differences in performance between publically and privately owned nonprofit nursing homes in Switzerland. In this chapter, we extend this literature. We examine the behavior of three types of Uruguayan private, nonprofit health care organizations and test for behavioral differences across the three types. We examine both differences in overall patterns of spending by the organizations and differences in the response of the organizations to an exogenous shock – a brief liberalization of government controls on membership fees. Uruguayan providers of primary health care services (outside the public sector which covers mainly the indigent, military families, and other dependents of the state) are required by a 1981 law to organize as nonprofits. They may choose among three types of organization: mutual benefit organizations (similar to consumer cooperatives), and two types of producer (doctors) cooperatives. Although they differ in their stakeholder and governance structures, all three types of organization face a very tight regulatory environment. The state sets prices for organization membership and other fees and mandates the range of services offered. Salaries, working conditions, and hours of doctors and technical staff are centrally negotiated with unions of medical workers. Because nonprofits do not compete in the market for basic health care services with for-profit providers, this context provides a view of ‘‘pure’’ nonprofit behavior, not influenced by competition with for-profits. At the same time, the strict regulatory environment should reduce variations in behavior across nonprofits. If significant differences in behavior exist in this regulatory context, more significant differences might be expected between types of nonprofits in more liberalized contexts. We draw on a unique dataset of Uruguayan health care organizations over the period of 1982–1990, the period immediately following the establishing of a mainly nonprofit system for delivering private health care.1 Although the survey covers a period two decades in the past, it illustrates cross-organizational differences in behavior. At the same time, the Uruguayan health care sector has undergone only very limited reform in the intervening period, leaving the structure of the three organizations, and the regulatory environment, basically unchanged in 2010, although there is significant discussion about reform. Taking advantage of this continuity, we conducted interviews with 11 Uruguayan doctors working in the three types of nonprofits during the spring of 2010, in order to understand organizational differences more clearly. We show that there are significant differences in behavior across organizational forms, even in a context where many behaviors are highly
264
JUAN JOSE BARRIOS AND MIEKE MEURS
regulated. These differences provide partial support for dominant models of nonprofit and cooperative behavior. For example, Union (producer) Cooperatives, which are predicted to maximize income per doctor, spend a larger share of total expenses on doctors’ remuneration than other types of organizations, which appear to have different interests. However, some results contradict standard predictions: Mutuals which, as a form of consumer cooperative, are expected to minimize costs to members, do not raise membership fees less than other organizations during a period of price liberalization. Interview evidence suggests some explanations for this and other findings. We conclude that more attention should be paid to governance structure when making predictions about nonprofit behavior.
URUGUAYAN HEALTH SECTOR IN THE 1980s Regulations established in 1981 require all private providers of basic health services to be nonprofit organizations (Grau Pe´rez & Lazarov, 1999). There is a long tradition, dating back to the mid-1800s, of nonprofit provision of basic health care through Mutuals, mutual benefit organizations based on ethnic solidarity. These organizations already met the new requirements. Other, for-profit, health care providers were required to restructure into nonprofits (Bertullo, Isola, Castro & Silveira, 2003, described in Section 3) below. In rural areas, where few nonprofits were organized through other channels, the rural doctors’ union (Federacion Medica del Interior, or FEMI) began organizing a minimum of one nonprofit provider per departmento (department, or county). By 1984, 36.5% of Uruguayans received primary health care from a nonprofit organization (Labadie, 1997), with the share rising to 47% by 1993 (Grau Pe´rez & Lazarov, 1999). The remainder of the population (by 1993 consisting mainly of low-income households without a formal-sector job and families of personnel of the armed forces and police)2 received basic health services from state organizations. Private, for-profit organizations continued to supply specialized (nonprimary care) services. Private, nonprofit suppliers of primary care face significant regulation. The state sets a minimum number of affiliates (members serviced by the health care organization), mandates the package of coverage provided, and sets rates for affiliation (membership) and co-payment prices. Regulating the scope of services, the state mandates that organizations supply basic, complete and egalitarian medical assistance in the areas of surgery, pediatrics, gynecology, general medicine, and preventive medicine,

as well as other services such as emergency treatment. A health care organization may supply services directly or outsource them to other nonprofit health organizations or to private clinics. In this case, the health care organization to which the affiliate belongs pays the providers. The system is organized as pre-paid insurance. The state collects a percentage of employees’ wages (from both employers and employees) and pays a membership fee (the ‘‘quota’’) to the health care provider chosen by the individual. If an employee’s contributions do not cover the quota, the state pays the difference, subsidizing health care to the less well-paid. Those affiliates who are not formal sector employees but wish to affiliate to private nonprofit providers must pay the full amount of the state-set quota directly to the medical institution. Health care providers have the right to reject affiliates with poor health records, who will then be serviced by public providers. Quotas, the main source of revenue for health care providers, were liberalized to a cap in 1983, and then liberalized completely in July 1984. A rapid increase in the price of membership led to a re-imposition of state-set membership fees in October 1985, however, which was still in place in 1990. Co-payments, the second largest component of health organization revenue, include additional payments for medicines, office visits, and other services. Like membership fees, these were briefly liberalized in 1984 and re-regulated in 1985. The remaining income of nonprofit health organizations comes from providing services to affiliates of other organizations (outsourced services). Since coverage and prices are regulated, competition among nonprofit organizations for affiliates (and thus revenue) is restricted to things like quality of attention to customers. Competition is further limited by a requirement that individuals affiliate to a health care organization located in their own department. Competition is stronger in Montevideo, where in all years of the study there were more than 20 health care nonprofits to choose from. In the majority of departments outside Montevideo (10 of 18), only one nonprofit provider existed during the entire period under study. In the remaining eight departments, two had three or more providers in every year from 1983 to 1990, whereas the other six had two providers in one to three of the years. Salaries in nonprofit health organizations are determined through tripartite negotiations between unions, representatives of the nonprofits, and the state. Collective agreements apply to all health organizations in which union members are employed. Doctors need not work more than 26 hours a month for any organization, allowing doctors to work in more than one
266

organization. Doctors in fact work in as many as five or six organizations – often a mix of public organizations, private for-profits, and nonprofits. The fact that doctors in different types of organization negotiate their salaries through the same unions apparently leaves little possibility for pay to vary across organizations.3 However, interview evidence suggests that individual organizations are permitted to vary salaries by about 20% from the negotiated rate (Interview 8, 2010). In addition to their salaries, doctors are paid a type of piece rate – an additional sum for each ‘‘medical act’’ that doctors perform. Additional variation in doctor pay may thus emerge across organizations, as these choose the number and type of medical acts performed and define medical acts, the definition of which appears to vary across organizations (Interviews 3, 7, 8, 2010). In 1991, payment for medical acts made up about 35% of total remuneration for doctors in Montevideo, and about 30% for doctors in the interior (PAHO, 2007). Finally, doctors may increase their incomes by shifting work – by keeping medical acts ‘‘in-house’’ instead of outsourcing them, or by outsourcing specific procedures from a nonprofit where they work but do not have access to the equipment necessary for the procedure, to another health organization where they also work, where they do have access to the machinery, or to a private for-profit clinic, which they might own (Interviews 2, 7, 9, 11, 2010). Other interview data suggest, however, that in most cases, the decision to outsource services is made by the technical director and is based on relative costs of in-house or outsourced services (Interview 9, 2010). Overall, throughout this period the behavior of Uruguayan health care organizations was highly constrained. They had only brief opportunities to vary the prices they charged for their services, little control over the package of services offered to affiliates, and limited ability to influence remunerations to doctors. Of course, organizations retained more control of some variables, including costs linked to organizational efficiencies and bargaining with suppliers, quality of the services to affiliates (wait times and doctor quality), and the working conditions of staff. Perhaps surprisingly, investments were not regulated, although they did require state approval.
TYPES OF ORGANIZATION In this section we draw on previous analyses of Uruguayan health organizations as well as interviews with stakeholders to describe the three types of Uruguayan nonprofit health care organizations. Eleven interviews (see appendix for details) were carried out with doctors, technical directors,
267
Governance and Behavior in Nonprofits
and board members during spring 2010. Since we cannot be sure that the information from the interviews accurately describes condition during the period 1982–1990, we simply highlight ways that interviews suggest differences from the established understanding of organizational structure. In addition to the secondary sources and interview data, we also draw on survey data from the Uruguayan Ministry of Health. The data includes financial results, utilization levels, and related information for each of the approximately 50 private, nonprofit organizations supplying primary health services over the period 1983–1986 and 1988–19904 (pooled, cross-sectional data). Since many of the organizations did not exist over the entire period, the exact number of organizations varies from year to year, as reflected in Table 1. The data was collected retrospectively, through surveys of the nonprofit organizations, in 1992. The previous literature (Labadie, 1997; Solari, 1992) describes the three types of nonprofit health organizations. Mutuals, described earlier, resemble consumer cooperatives since ‘‘consumers’’ (affiliates) elect other affiliates to the Board and exercise control over the organization. Doctors working in Mutuals are required to be affiliates of the Mutual (Interview 9, 2010). Doctors may be elected to the Board either in their capacity as affiliates, or as representatives of the staff. Other employees may also have seats on the Board (as staff), but all staff are minority members. Interview evidence (Interviews 7, 11, 2010) suggests that governance of Mutuals may not always reflect broad affiliate interests. Board membership Table 1.

is often limited to a small group of insiders, sometimes organized around the families of founding members, who rotate through the Board periodically. Insiders may collude to present a limited number of lists (sometimes only one) at the time of elections, excluding other affiliates from power. Boards were also reportedly sometimes ‘‘captured’’ by businessmen-affiliates, interested in selling goods and services to the organization. Other health organizations are organized as medical cooperatives, resembling producer cooperatives. These cooperatives can in turn be subdivided into two different types. Guild, or Union, Cooperatives are producer cooperatives organized under the auspices of doctors’ unions. These cooperatives operate independently of the unions in most respects. The board of directors is elected from among doctors who are members of the producer cooperative, by the other member-doctors. In this case, all doctors working in the cooperative are both members and workers. There are two doctors’ unions, one serving doctors working in Montevideo (Sindicato Medico del Uruguay) and the other representing doctors working in other departments (Federacion Medica del Interior, or FEMI). The Montevideo union organizes only one Union Cooperative, CASMU (Centro de Asistencia del Sindicato Medico del Uruguay). CASMU is by far the largest health care organization in Uruguay. There is at least one Union Cooperative organized by FEMI in every department outside Montevideo, organized by the union after the shift to the all nonprofit national system in 1981. In some cases, there is more than one in a department. Serving more rural areas, these tend to be much smaller than CASMU. The second type of medical producer cooperative, Doctors’ Cooperatives, are created, and often funded, by doctor-members. Members of the Board are elected from among these doctor-members. In Doctors’ Cooperatives, the member-doctors also hire other, non-member doctors (Labadie, 1997; Solari, 1992). These non-member doctors cannot be elected to the Board.5 Some are regular employees, for whom the organization pays social security contributions. But Doctors’ Cooperatives also reported hiring contract workers. These contract workers may later be offered a chance to become a formal employee (or even a member of the producer cooperative). Although Mutuals are organized by health care consumers, around principles of ethnic or religious solidarity, and then hire doctors, Doctors’ and Union Cooperatives are organized by doctors themselves. The choice to organize as a Union Cooperative, as opposed to a Doctors’ Cooperative, appears to depend in part on when the organization was formed and, relatedly, on who initiated the organization.
Governance and Behavior in Nonprofits
269
FEMI took the lead in organizing at least one nonprofit health care cooperative in each department after the passage of the 1981 law. This may have been an important service to union members, providing employment to Uruguayan doctors who faced a flooded labor market (PAHO, 2007) but had limited capital for start up costs and other organizational problems. FEMI also appears to offer some other advantages to its Union Cooperatives, such as the ability to ‘‘capture’’ members from other unions, subcontract work from public hospitals (where union members also work), and so on (Interview 4, 2010). Private, for-profit Doctors’ Cooperatives, or group practices, may have simply turned themselves into nonprofit a Doctors’ Cooperative at the time of the 1981 law, using capital already in hand. But in rural areas, pre-existing group practices could also work with their union (FEMI) to become a Union Cooperative (Interview 2, 2010). One factor in the choice of organizational form may have been the practice in Doctors’ Cooperatives of hiring non-member doctors as employees. Interviews with members of six Union Cooperatives suggested an important difference from this prevailing description, however. Interviewees explained that (at the time of the interviews in 2010) Union Cooperatives, like Doctors’ Cooperatives, often hire non-member doctors (Interviews 2,3,4, 2010). This ‘‘degeneration’’ reportedly occurs when the founding group of doctor-members can no longer manage the workload, but chooses not to recruit additional doctors as regular cooperative members (Interview 7). It is thus possible that the degeneration occurred later in the Union Cooperatives than in the Doctors’ Cooperatives, and governance differences may still have existed at the time our data was collected. Many Union Cooperatives were new in 1983, and possibly had not yet reached capacity, whereas Doctors’ Cooperatives were more likely to be pre-existing practices transformed after the 1981 law. Uruguayan nonprofit health organizations clearly differ in the make-up of their stakeholders and their representation on the board of directors. Boards at Mutuals are dominated by affiliates, whereas producer cooperatives’ Boards are dominated by doctors. It is less clear whether the two forms of producer cooperatives are distinct. Other differences among the types of organization that may affect behavior include differences in size, capital stock, services offered, and the age of members. The period 1983–1990 was one of rapid development in the Uruguayan health sector, as for-profit organizations restructured into nonprofits and new nonprofit firms were created to meet growing demand. After a 1983 regulation established a minimum number of affiliates for health care nonprofits, small organizations closed or merged, and the
270
JUAN JOSE BARRIOS AND MIEKE MEURS
number of Mutuals fell. The share of Union Cooperatives in the nonprofit population increased as a result, but the number of Mutuals stabilized at about 12, or 24% of the population of nonprofits, at the end of the period. As seen in Table 1, the organizations were divided fairly evenly between the three forms. (Because CASMU is uniquely large, we treat it as a distinct type of non-profit, although it is Union Cooperative.) As seen in Table 2, membership in these organizations grew significantly over the period 1983–1990. There are significant differences in average number of affiliates by organizational type however, and these remain fairly stable. As noted earlier, CASMU, the Montevideo Union Cooperative, is significantly larger than any other organizational type. Measured by number of affiliates, Mutuals are the next largest on average, whereas Doctors’ Cooperatives and Union Cooperatives outside Montevideo are fairly similar in terms of average membership. Over the period, we see a slight shift in membership from Doctors’ Cooperatives to Union Cooperatives. Between 1983 and 1990, capital stock of the nonprofits grew much faster than membership (Table 3). There were important differences in the amount of capital acquired, however, with Mutuals and the relatively newer Union Cooperatives gaining capital faster than Doctors’ Cooperatives or the already-capital intensive CASMU. These differences in membership and capital stock may reflect different scale economies, particularly affecting the ability of organizations to offer services in-house and to offer (remuneration-enhancing) medical acts to doctors.

BEHAVIOR OF NONPROFIT ORGANIZATIONS In this section, we develop hypotheses about behavioral differences across the different types of nonprofit organization, drawing on the literature on stakeholder interests and nonprofit behavior, and the literature on behavior of producer and consumer cooperatives. Preference differences among diverse stakeholders may create conflicts over nonprofit objectives. Because nonprofits are not subject to take-over threats, and to the extent that they do not face competition from for-profits, the diverse stakeholders make internal organization central to nonprofit behavior (Bachiegga & Borzaga, 2002) and generalizations about nonprofit behavior difficult. We use information about organizational structure and standard theory of cooperative behavior to develop hypotheses about behavioral differences. Uruguayan health care organizations do not have outside donors, leaving managers, workers, and consumers as relevant stakeholders. Managers may have preferences over the growth and financial health of the organization, as a larger, financially more successful nonprofit may give a manager more power with respect to other nonprofits and public officials. Managers’ preferences may also include product quality (Glaeser, 2002). Workers in health care non profits include doctors, as well as other medical and nonmedical staff. Their preferences include pay and working conditions. Worker preferences may also include product quality, as nonprofit workers
272
JUAN JOSE BARRIOS AND MIEKE MEURS
may choose nonprofit employment as a result of their commitment to its goals (DeVaro & Brookshire, 2007; Glaeser, 2002). Since membership fees, co-payments, and the package of benefits are regulated, relevant consumer interests center on quality. The diverse stakeholders may influence organizational behavior in several ways. The distribution of formal control rights, including membership on the board of directors, is important (Weisbrod, 1975). Control of information and technical knowledge is another channel of influence. In medical worker cooperatives (hospitals), doctors’ control of technical knowledge may lead hospitals to follow their preferences even when doctors do not constitute a majority of board members (Pauly & Redisch, 1973). Similarly, proximity of certain stakeholders to managers or Board members can increase these stakeholders’ control over important decisions (Glaeser, 2002). Formal control rights in the Uruguayan health care nonprofits vary according to their organizational form. In Mutuals, consumers make up the majority of board members, although doctors may also be represented as both consumers and workers, and other workers may also have minority representation on the Board. In Union and Doctors’ Cooperatives, the board of directors is elected from among doctors who are members of the cooperative, by the other member-doctors. An important difference between the two forms of producer cooperatives may be the nonrepresentation of non-member doctors (workers) on the Boards of Doctors’ Cooperatives during the period 1983–1990. Where a Union Cooperative is the only nonprofit in a department, doctors will also be consumers in that cooperative, in effect giving consumers some input into decisions. All health care nonprofits must have a doctor as their technical director, providing similar informal control rights to doctors across organizational forms – via both legal recognition of doctors’ special knowledge and proximity of the technical director to management and the Board. Other means of influence via proximity may vary across organizational form. In Mutuals, insider groups of consumer-members may interact closely with the Board and management, while in Doctors’ and Union Cooperatives, senior and founding-member doctors are more likely to do so. Standard models of cooperative behavior assist us in developing predictions about how different types of stakeholder influence translate into behavior. Although standard models assume a more homogeneous set of stakeholders (workers or consumers) than is actually found in Uruguayan nonprofits, they capture the basic differences between the most influential stakeholders in consumer and producer cooperatives.
Governance and Behavior in Nonprofits
273
Many standard predictions of these models will not hold, however, given the highly regulated context of Uruguayan health care cooperatives. For example, a standard model of consumer cooperative behavior (Clark, 1952) posits that cooperatives governed by consumers will minimize per-unit costs. Since the fees and co-payments consumers pay are set by the state, costs to Mutual members are not linked to actual costs of providing the service. Consumer-members may have little incentive to minimize costs. We posit that they may instead maximize quality, by raising doctor remuneration, in order to hire high-quality doctors, by hiring more doctors, to reduce wait time, or by purchasing machines for (convenient) in-house provision of services. Doctors on the Board and the technical director might attempt to influence consumers’ definition of quality, to bring this definition more in line with their own preferences. One important exception to this behavioral prediction, however, would be the period of quota liberalization in 1984–1985. During this period, consumer-members of the Mutual Boards faced a direct link between cooperative behavior (quota-setting) and their costs of health care, and predicted consumer interests in low costs should have affected the behavior of Mutuals. Mutuals would be expected to raise quotas less than other types of organizations. If the capture of Mutual Boards by insiders, described in the interviews, is important, however, the expected cost-limitation would not occur. Standard models of producer cooperatives suggest they maximize net income per member, and as a result choose inefficiently high levels of output and investment to achieve this (Domar, 1966; Pauly & Redisch, 1973). In the Uruguayan context, where net income cannot be distributed, the expected behavior might take the form of increases in doctor remunerations and, as in the standard model, greater investment in equipment, which can be used to increase doctors’ remunerations (for medical acts). Producer cooperatives would also be expected to limit outsourcing of services, in order to increase payments for medical acts (unless, as interviews suggest, doctors outsource services to their other places of employment, where they expect higher remuneration). Doctor’s Cooperatives appear to be a ‘‘degenerate’’ form of producer cooperative (Abell, 1983), however, with members hiring non-member workers in a traditional employment relationship. Since hired workers cannot formally influence decisions, these ‘‘hiring’’ cooperatives may continue to maximize remuneration per member, but this will no longer be equivalent to maximizing remuneration per doctor-producer. The extent to which Doctors’ Cooperatives are expected to behave differently from Union
274
JUAN JOSE BARRIOS AND MIEKE MEURS
Cooperatives depends on their relative dates of degeneration, something that we cannot measure using our data. However, based on descriptions of the development of the sector, we expect a difference in behavior during the period under study. Given the highly regulated context, we focus our analysis on four types of behavior that may vary across organizational type. The first three reflect differences in overall behavior: remunerations to doctors, investment in medical equipment, and outsourcing. A fourth behavior is the response to the liberalization of quotas 1984–1985. Hypothesized differences with respect to remunerations can be summarized as follows: Union Cooperatives (traditional producer cooperatives) will spend relatively more on doctors’ remunerations than Doctors’ Cooperatives, as the Union Cooperatives seek to maximize remunerations per doctor.6 Doctors’ Cooperatives are expected to maximize revenue per member, which may mean limiting remunerations to non-member doctors and shifting work onto these employees, as member doctors restrict themselves to the best-remunerated medical acts, including those at other places of employment, possibly lowering remunerations to doctors overall. However, if interview evidence that Union and Doctors’ Cooperatives do not differ in their level of ‘‘degeneration’’ applies to the period 1983–1990, no differences are expected in doctors’ remuneration between Union and Doctors’ Cooperatives. Because of uncertainty about how Mutual members define quality, Mutual behavior is harder to predict. Relative spending on doctors’ remunerations will depend on the extent to which Mutual members define quality as doctor quality, and whether remunerations are an effective means to attract such doctors. If Mutual members define quality mainly as doctor quality and higher remunerations attract doctors, Mutuals may not behave differently from Union Cooperatives. If Mutuals define quality as things like in-house provision of low piece-rates services, however, doctors’ remunerations in Mutuals will differ from those in Union Cooperatives. With respect to investment, Doctors’ Cooperatives are likewise expected to invest relatively less in equipment than Union Cooperatives, investing in equipment needed for medical acts of members, but not investing in machines needed to ‘‘capture’’ medical acts for non-member doctors. However, if Union Cooperatives and Doctors’ Cooperatives do not differ in their level of ‘‘degeneration,’’ no differences are expected in investment between Union and Doctors’ Cooperatives. The behavior of Mutuals will depend, again, on how members define quality. Mutuals might spend relatively less on investment if it is not needed to attract high-quality doctors or if

Table 4. Summary of Hypotheses. H1: Union Cooperatives will spend relatively more on doctors’ pay than other forms of organization H1u : All nonprofits will behave similarly H2: Union Cooperatives will spend relatively more on outsourcing than other forms of organization H2u: All nonprofits will behave similarly H3: Union Cooperatives will spend relatively more on investments than other forms of organization H3u: All nonprofits will behave similarly H4: Mutuals will raise membership fees least during liberalization; Union Cooperative most H4u: Nonprofits will respond similarly to liberalization
members do not prefer in-house services (external services may be ‘‘higher quality’’). If Mutuals are captured by insiders, as interviews suggest, this should result in relatively less investment.7 Another set of hypotheses relates to the outsourcing of services. In the Uruguayan context, where doctors are paid by medical act, Union Cooperatives are expected to outsource less than Doctors’ Cooperatives as they seek to maximize remunerations per doctor. Once more, Mutuals’ behavior depends on how quality is defined. They may outsource more, if outsourced services are seen as higher quality. Or they may outsource less, if in-house services are seen as higher quality (perception in-house doctors may use their position to defend). Finally, we examine whether organization types respond differently to the liberalization of quotas in 1984. We expect that Union Cooperatives, maximizing remunerations, will raise quotas most, whereas Mutuals, where consumers are majority Board members, will raise quotas least. Doctors’ Cooperatives, unconstrained by members, are expected to behave more like Union Cooperatives, more if they are ‘‘degenerate.’’ Hypotheses are summarized in Table 4.
ANALYSIS OF THE URUGUAYAN CASE In examining differences in doctors’ remunerations, investment, and outsourcing of services, we normalize these expenditures as a share of total expenses. Because this risks introducing other, distorting, factors into our
276
JUAN JOSE BARRIOS AND MIEKE MEURS
outcome variable – those affecting total expenses – we also did all of the analyses normalizing by number of affiliates, as a robustness check. Other than slightly reducing the significance of the regressions, the use of the spending-per-affiliate measures does not change the results.8 Table 5 shows variation in the outcome variables across organizational type. As expected, Union Cooperatives and CASMU spend a larger share of total expenses on payments to doctors than Mutuals or Doctors’ Cooperatives. As expected, Union Cooperatives also spend the least on outsourced services. However, for investment, we do not see the expected differences. Union Cooperatives (other than CASMU) have lower average levels of investment than Doctors’ Cooperatives or Mutuals. Surprisingly, we see quite a bit of variation in quotas per member, although for most of the period quotas were set by the state. Fig. 1 shows that this is not simply a result of differing responses to the liberalization in 1984–1985. Differences exist in every year, perhaps due to noise in membership data or a discrepancy between the dates that quotas are paid and membership is counted. Importantly, Fig. 1 shows differences in the change in quotas per member during the 1984–1985 liberalization, especially in 1985, before the re-regulation, which was announced in advance. In the regression analysis, we control for variables other than organizational form which might affect behavior. All variables are annual reported values for each organization. We control for size of organization (number of

affiliates). Size may measure economies of scale in in-house service provision and affect outsourcing and also investment. Similarly, we control for capital stock (fixed assets, in constant pesos). Different types of organization face different competitive environments. CASMU is located in Montevideo, so faces significant competition. Doctors’ Cooperatives and Mutuals are never monopolies, but Union Cooperatives often are. These differences in competitive environment may affect organization behavior, and we control for this in two ways. To control for possible competition for affiliates, we include the number of other health care organizations operating in the same department. This varies from 0 in every year in many departments to over 30 in the early years in Montevideo. As a control for competition for doctors (the labor market for which faces a significant surplus in Montevideo but may face a shortage in less desirable areas), we include a dummy variable taking a value of 1 for Montevideo and the neighboring departments of Canelones and San Jose, and a 0 for all other departments.9 The need for doctor visits and other services may increase with age, and some of the older organizations may have older affiliate populations. We control for the share of affiliates older than 65 years. Finally, the sector was evolving in significant ways over the period 1983–1990, as an increasing share of the rural population was incorporated into the system, new organizations entered and matured, and smaller
278
JUAN JOSE BARRIOS AND MIEKE MEURS
organizations were eliminated. To control for this, as well as cyclical economic impacts, we include a complete set of year dummies, with the first year, 1983, as the omitted category. When comparing the way the 1984–1985 liberalization affects quota-setting across organizational types, we replace the full set of year dummies with an interactive variable. We interact organization type with a dummy for the year 1985 (the year of most change in quotas, seen in Fig. 1). Our variable of interest, organizational form, is measured as a set of dummy variables, with CASMU, the very large Montevideo Union Cooperative, as the omitted category. Means and standard deviations of these variables are presented in Table 6. The econometric model takes the following form: yit ¼ axit þ bzit þ where yit represents, alternatively, the four outcome variables used in the four regressions: Doctors’ incomes, spending on outsourced services, and investment, as a share of current expenses, by organization, at time t, and change in quotas per member over the previous year, in thousands of constant pesos, by organization i, at time t, all for t ¼ 1983–1986 and 1988–1990. Because we estimate investment and change in quota per member using the year-on-year change in capital stock and quotas, these regressions do not include 1983, and 1984 becomes the omitted category for the year dummy. Further, we use the natural log of the investment share variable in the regression, in response to the extreme distribution of this variable (which ranges from 0.51 to 75.52).

xit represents the set of dummy variables for organization type for each organization at time t, although no organization switches type between years; CASMU, the very large cooperative of the Montevideo doctors’ union, is omitted, and zit represents the other explanatory variables for each organization at time t. Capital stock and number of affiliates are clearly affected by the behavioral outcomes examined here – investment in one period affects the capital stock in the next, and number of affiliates will be affected by organization spending on doctors and investment. Here, we include capital stock and affiliates as independent variables to control for the impact of current levels on current year behavior. We estimate the regressions as Robust OLS regressions in STATA.10 The regression results are presented in Tables 7 and 8. We begin by discussing Table 7. The findings confirm that, controlling for differences in size, competitive environment, capital stock, patient demographic, and year, there are significant behavioral differences across organization type. One important finding is that CASMU, the omitted category of organization, behaves differently than any other type of organization. Compared to all other types of health care nonprofit, CASMU spends a lower share of its expenses on doctors’ pay and investment, and a greater share on outsourcing. Although we have attempted to control for the important differences in size and the competitive characteristics of location, perhaps these controls are imperfect. Because CASMU is a single cooperative, located in Montevideo, the CASMU organizational variable may be picking up specific characteristics of this location, in addition to organizational differences. CASMU has many possibilities for outsourcing, including to other clinics where CASMU doctors work, a practice mentioned by interviewees. This consideration may also drive decisions about investment. Desirability of employment in this large, well-located and well-endowed organization may limit the need to raise doctors’ salaries to attract and retain doctormembers. All three other organizational types spent a significantly larger share of expenses on doctors’ remunerations than CASMU. As expected, spending in Union Cooperatives, which are predicted to maximize remunerations per doctor, was higher than in other forms. (The coefficient on Union Cooperatives is significantly larger than that on Doctors’ Cooperatives and Mutuals at a level of po0.001.) However, spending on doctors’ remunerations did not differ significantly between Mutuals and Doctors’ Cooperatives. As suggested earlier, Mutuals may not seek to reduce this cost, preferring to spend more to attract high-quality doctors. Spending on doctors’ remunerations was negatively

correlated with the number of competitors, as expected. Location in the Montevideo region was not significantly related to the share of doctors’ remunerations in total expenses, except to the extent that the CASMU dummy picks up this effect.

Looking at outsourcing of services, Union Cooperatives (other than CASMU) again behave as expected.

for in-house medical acts to member-doctors. Again, the small difference in the coefficients on the dummies for Mutuals and Doctors’ Cooperatives is insignificant. After controlling for the behavior of CASMU, location in the Montevideo region is negatively related to outsourcing. Surprisingly, capital stock does not affect outsourcing, controlling for other factors. Organizations with more members and with a greater share of members over 65 years outsource relatively less.11 Investment behavior also follows the expected pattern of significantly higher levels of spending by the Union Cooperatives, compared to Mutuals or Doctors’ Cooperatives (po0.01). Spending more on investment may permit more medical acts by doctor-members. As with other behavior, the small difference between the coefficients on the dummy variables for Mutuals and Doctors’ Cooperatives is not significant. Organizations with more affiliates spend more, although the effect is very small. Being in the Montevideo region and having a greater share of older members are also associated with more spending on investment. Year is significantly related to relative spending on investment, with a steady rise in the size of the coefficients over the entire period. Finally, we consider whether the different types of organization behaved differently during the brief liberalization of quotas (Table 8). In this regression, we replace the year dummy for 1985 with an interactive variable, interacting 1985 with organization type. As might be expected, CASMU again behaves differently from all other organizational types, raising quotas the least. Among other forms of organizations, Union Cooperatives raise quotas the most, as predicted. The coefficient on Union Cooperatives is significantly different from that on Doctors’ Cooperatives and Mutuals (po0.10 and o0.05, respectively). Contrary to expectations, however, Mutuals do not raise quotas the least. The coefficient on the dummy for Mutuals is not significantly different from that on Doctors’ Cooperatives. This suggests that the behavior of Mutuals may not be driven by consumers’ interests. Perhaps, as suggested by interviews, the Boards governing Mutuals are often captured by insiders interested in selling (relatively high cost) services or materials to the cooperative, thus preferring high quotas to cover such costs.
CONCLUSIONS Using data on Uruguayan health organizations for the period 1983–1986 and 1988–1990, supplemented with interviews, we have examined the relationship between governance structures and behavior in nonprofit health

283
care cooperatives. We find some evidence that different types of nonprofits behave differently, despite a tightly regulated environment with prices and wages set externally. As suggested by the literature on nonprofit and cooperative behavior Union (producer) Cooperatives spend a larger share of total expenses on doctors’ remuneration than Doctors’ Cooperatives (a possibly more degenerated form of producer cooperative) and Mutuals, where consumers have broader interests, beyond raising doctors’ pay. In some cases, the theory on cooperative behavior does not predict outcomes, however. Mutuals, which are predicted to further consumer interests, did not raise membership fees less than other forms of organization during a brief price liberalization. Interview evidence, which provides additional information on governance structure, suggests that the behavior of Mutuals may be driven more by the interests of small groups of insiders than by those of consumer-members as a whole. Another insight from the interviews, the possible importance of hired doctors in Union Cooperatives, suggested behavioral commonalities with Doctors’ Cooperatives not seen in the data. This may be due to changes between the period of the survey and the time of the interviews (a gradual degeneration of Union Cooperatives since 1990), or perhaps the small interview sample of Union Cooperatives, where hiring non-member doctors was reported to be common, is not representative of Union Cooperatives as a whole. The difference in behavior across organizations with differing governance structures provides support for recent efforts to develop more fine-grained predictions of behavior of nontraditional firms (Ben-Ner & Gui, 2003). It also suggests that empirical tests of behavioral differences between traditional and nontraditional firms will be more meaningful if the governance structure of nontraditional firms is common, and clearly specified. An important limitation of this study is our inability to control for the exact timing of degeneration of producer cooperatives, and this would be one important element of governance structure to consider in future data collection.

individuals seriously burned, and the Fondo Nacional de Recursos (National Resource Fund), a decentralized publicly funded organization that funds high-cost, complex medical treatments, often through private providers. 3. As will be discussed further later, doctors in Montevideo (regardless of the type of organization they work in) are organized by a different union than doctors in other provinces and, facing a much larger supply of doctors in Montevideo, members of this union typically get somewhat lower salaries than members of the union which organizes doctors outside Montevideo. 4. The data is meant to be a complete series from 1982 to 1900. However, data for 1982 and 1987 are missing. 5. Both types of producer cooperatives have rules which allow non-member doctors, workers and affiliates to be represented on the Board, but this possibility has not been exercised in practice. 6. Where Union Cooperatives are the only nonprofit health care provider in a department, the doctor-members will also be consumers. This will not be true for all Union Cooperatives. However, it may have an impact on behavior if doctorconsumers define quality as doctor quality. 7. Examples of capture had to do mainly with contracts for consumables. 8. Results available from authors. 9. A Montevideo dummy might be preferable for capturing specific characteristics of this labor market (as will be discussed later). However, CASMU, a unique organization type, is located only in Montevideo, creating a collinearity problem with a Montevideo dummy. Dropping CASMU from the sample is an alternative strategy. Dropping CASMU does not affect results regarding the behavior of other organizational types, so we include CASMU in the sample. 10. The Robust OLS regression in STATA uses Cook’s D to select (and then drop) outliers. The use of the Robust Regression produces almost identical results to the standard OLS regression, but results in slightly higher levels of significance because of improved standard errors. 11. This somewhat surprising result may appear linked to overall higher costs, which would increase the denominator of the dependent variable. However, as noted earlier, this result also holds when measuring outsourcing as expenditure per member.

PART IV FREE TRADE AND THE ECOLOGICAL EFFECTS OF ALTERNATIVE SOCIO-ECONOMIC SYSTEMS
CAPITALISM, ECONOMIC DEMOCRACY, AND ECOLOGICAL DESTRUCTION OF OUR PLANET Jaroslav Vanek ABSTRACT There is a fundamental difference between the impacts of two alternative systems of economic organization: capitalist or fully democratic. The latter, based on democratic decisions based on personal rights, including in the area of enterprise management and organization will, in many contexts, protect the natural environment because the decision makers live in and are permanently exposed to that environment. By contrast, the capitalist firm and the system based on it and on profit maximization (where the often ‘‘atomized’’ owners have never even seen their firm) will tend to avoid where possible all environmental-related costs, and thus hurt the natural and human environment. Thus public regulation of capitalist firms will be far more called for than in the case of economic and full democracy. In the chapter that follows I make an attempt to substantiate these claims.

INTRODUCTION Probably the most significant issue affecting the consciousness of all people, whether in the rich or the poor parts of the world, is the ecological impact on – or gradual destruction of – our planet. The purpose of this study is to examine this issue from a rather new and unusual point of view, that of socioeconomic systems. To be more precise and to clarify our argument, it is desirable to define more carefully what we mean by ecological impact. People and in general human societies by their various activities produce what we refer to as ‘‘ecological impact’’ on the world we live in. What concerns us here is such impact bearing on the wellbeing of humankind. It can be positive or negative, and it is the second that will concern us here, as much as the concern of all those who are considering the ecological issue. The typical subject under the ‘‘ecological’’ heading includes such things as global climate change and its effect on people, such as the effect of global warming on the life of people in low-lying parts of the planet or impact of global warming on loss of rain, irrigation, and food production. The typical reaction of world governments and institutions is the attempt to identify precisely the extent of such impacts, and where possible to cope through policy or otherwise with the negative effects or impact of such ecological developments, such as the Kyoto agreements or the meetings at the end of 2009 in Copenhagen. All this is well known, and experts and politicians better qualified than this writer are or should be dealing with the subject. But there is a related issue very rarely if ever noted today that should also interest us and that may be quite critical for the ecological strategy of the world, and even of vital significance in the long run for the welfare of humanity. This topic is the socio-economic system under which the world economies or countries are operating. A Stalinist or soviet-type system certainly would have had its – probably most negative – effect on the world ecology. A fully monopolistic capitalism, if it had not been mitigated by corrective antitrust legislations and action, would have had its own effects: The White House and the whole world economy would have most likely been ‘‘owned by the Rockefellers’’ but the world ecology under a benevolent dictator might have been better because the ‘‘dictator’’ would have preferred cleaner air for himself and his friends. The system of regulated oligopolistic competition under which the world is (more or less) living under today has its own effects on world ecology –
Capitalism, Economic Democracy, and Ecological Destruction of Our Planet
291
and we know that the present-day state of the world ecology is far from desirable. And it is precisely the policy action attempted by the world governments that is aimed at corrective action. But there is another economic system not as well known but certainly well understood in both theory and concrete observation that is likely to yield better results for the world ecology. It is the system of what we refer to as economic democracy – or full democracy where all aspects of social existence, including the sphere of production, are based on democratic principles. By this we understand a system of one person one vote by those involved; instead of one person one vote in the political sphere and one dollar one vote in the rest of human endeavor. It is this comparison, as much as we can, that we want to endeavor in, between the systems of oligopolistic capitalism and a system of economic democracy, both operating under free competitive market conditions that we want to study here from the point of view of their respective ecological impacts on life on our planet. We will have a lot to say, both in theory and in practice, in the sections below. But perhaps one very concrete example can illustrate what we understand by such a comparison. Take the well-known and in some sense tragic situation where most transportable products are produced in China because of the more than one thousand percent wage differential. Crudely speaking, the oligopolistic capitalist solution is to close factories and eliminate jobs in the United States and produce in China for the American markets. This leads to misery for not only our unemployed workers but also ten thousand miles worth of transportation and fuel consumption, not to mention corruption and income maldistribution in the world economy. Contrast this with the ‘‘theoretical’’ fact that the workers of American factories cannot move to China, but if they could control democratically their living and working conditions, they could stay home and seek solutions – which we will speak about presently – which avoid both the human and the ecological negative impacts.
THE THEORETICAL ANALYSIS For the purpose of theoretical analysis we ought to start with a more formal definition of the two systems we want to consider. The capitalist system or economy is usually defined as a market economy where individual firms are motivated by the desire to maximize profits.
292
JAROSLAV VANEK
The profit to be maximized is defined as revenue (R) minus labor costs (L) minus all other costs (O). But maximization of R implies minimization of L and O. To the extent that the managers of the capitalist firms can minimize L or O they will do it. And in both situations such action will or may have a negative ecological impact. We cannot go into the detail of such actions, but we know that this can lead to significant global losses of wellbeing. The usual argument given by the apologists of capitalism is that competitive labor and product markets give the managers constant market prices. But we also know that in many cases – cases that can be enumerated by the reader in thousands – such conditions do not apply, as in the case of dumping lethal chemicals into public waterways or into public grounds; or the moving of production abroad (outsourcing) while throwing labor out of jobs. In fact, if we include into our analysis also the uncompensated use of polluting energy, all these impacts of the capitalist system can be subsumed as belonging to the ecological destruction of the planet. Perhaps more concretely and specifically the negative impact on L by virtue of the action of profit-maximizing capitalism can be referred to as the minus sign syndrome (MSS). But there are other aspects of modern capitalist organization which further strengthen the comparative negative ecological impact. In the present context of ecological impact, a self-employed or family enterprise would appear as much better, because first of all the MSS is not present where the self employed producer maximizes his or his family’s wellbeing – which includes scores of objectives. And some of these objectives can control the destructive impacts on the environment, because the worker or his family live in or very near the environment affected. The democratic or self-managed firm is not ideal, but in many respects it resembles the individual producer. Above all, it also is not subject to the MSS because it does not maximize profit but also maximizes the well-being of its members, subject to some democratically determined principles of overall net income distribution. Also, since the working members of the firm live within the natural environment of the enterprise, they will tend to protect that environment for their own benefit. Some of the negative ecological impact may of course remain, but the overall positive tendency cannot be denied for the democratic firm. But there are other and equally significant comparative advantages of the democratic forms of firms and industries, in that they are less or not wasteful of resources of many kinds. This thesis takes a little more explanation.
Capitalism, Economic Democracy, and Ecological Destruction of Our Planet
293
Given these objectives of the two types of economies and given technologies – for the moment assumed to be identical for both – we must begin our inquiry by studying the respective equilibria (or solutions) of firms and industries. The typical technology as we encounter it in the real world is one subject to increasing returns to scale, followed by constant returns to scale or even diminishing returns for very large scales of production. Given such technologies and given competitive markets, the capitalist firm will grow to a size beyond the scale of constant returns because at such returns the managers would always try to increase profits by increasing level of outputs. And if, as is most often the case, the range of constant returns is large or even infinite, the firm would tend to grow indefinitely up to a point where the demand becomes less than infinitely elastic, and the firm tends to become monopolistic. This is precisely the situation that we described by the reductio ad absurdum of the ‘‘Rockefeller White House.’’ The negation of the absurd solution then is sought through antitrust legislation. But that solution then leads to another and perhaps worse can of worms through creating a situation of oligopolistic competition. Thereby a few firms compete through high pressure advertising and increasing demand and use of resources beyond what is reasonable, while ‘‘brainwashing’’ the population and turning its consciousness to vulgar materialism and seeking ever newer products – instead of life enjoyment through more moral and ecological endeavors. By contrast, the solution of a democratic firm and industry is far more ecological in many respects. First of all the democratic firm maximizing income per member or per worker will find its equilibrium at the point of maximal efficiency of production factors – not growing beyond that point and leading to monopolistic results (see my General Theory of Labor Managed Economies) and not calling for antitrust or oligopolistic results. Moreover the democratic solution, thanks to relatively smaller and less aggressive firms, will tend to avoid the ecologically undesirable solutions just noted for the capitalist oligopolistic solution. In addition to using a formal analysis of sales promotion and advertising, ceteris paribus, the capitalist firm will tend to use more wasteful advertising (pushing its products) than the democratic firm that may not even use such techniques. One of the significant factors of the democratic firm adjusting to optimal allocation of its resources is that it can control its working hours. This is most likely to lead to reduced outputs as compared to a capitalist situation, thus reducing the pressure on resources including energy consumption. The capitalist to maximize profits must increase or control at a high level the
294
JAROSLAV VANEK
labor inputs because this is required for his profit; whereas the working community can maximize its welfare through taking out some of its satisfaction through leisure, especially since the labor incomes per hour can be higher than the capitalist wage. Using a somewhat similar train of thought, it is possible to expect a difference between the two economic solutions, favoring the democratic firm with respect to the quality of the product – better quality requiring often less material or even less energy. The self-determining working community will often choose or prefer more precise and enjoyable effort; whereas the capitalist will often introduce brain-wrecking and physically demanding work on the assembly line of inferior products with repetitive action at high speed. But such production at high volume of lesser quality goods will call for more material and energy per unit of output. A reductio ad absurdum may illustrate our argument: It might be most attractive and agreeable to the worker to produce every part of an automobile entirely ‘‘by hand.’’ But such a less stressful solution could hardly be acceptable in modern manufacturing. One of the most significant causes of ecological deterioration is transportation and its related consumption of fuel that pollutes the environment. And thus if there are systemic causes of reduction of transportation through reduced distances, there is a definite result of ecological improvement. There are several reasons to expect such positive effects from an economy based on fully democratic principles, not only political, but also and especially in the organization of production. The first positive effect we noted already in the introduction related to the democratic creation of ‘‘offspring’’ production units by self-managing or worker-owned firms. By contrast to the capitalist firm that shuts down in the United States and moves to China, the democratic firm – as illustrated by the cooperatives of Mondragon – preserves the jobs at home in Spain and even increases the economic performance by creating offspring in some other parts of the world with significantly lower incomes and needed employment. This policy can have many ecological results. Instead of thousands of miles to and from China, the distances involved by the offspring firm can be reduced. There can occur a division of labor between more and less complex products between the mother firm and the offspring. Often also the offspring firm is located closer to the loci of consumption or demand; thus the transportation is significantly reduced. Another reduction of transportation effect is likely to occur through an increased number of competitive firms, smaller in equilibrium than the capitalist oligopolistic firm. A theoretical example will illustrate the point: suppose that a market in the United States is supplied by a single
Capitalism, Economic Democracy, and Ecological Destruction of Our Planet
295
oligopolistic firm from the center of the country, in Chicago. If the market is supplied more locally by a number N of democratic firms evenly distributed around the country, and the transportation distance of the capitalist centralized alternative is say, a trillion miles (from factory to equally distributed consumers/users) the transportation aggregate distance from the N democratic firms equally distributed around the country will be equal to a trillion divided by square root of N. For a more precise derivation of this result see Chapter 25 of my Unified Theory of Social Systems (available at http://hdl.handle.net/1813/642). In fact, this theoretical result has a very significant concrete manifestation in the modern development of thousands of local farmers markets, where a single supplier or a supplier region in California is replaced by thousands of local growers selling in farmers markets. The reduction of distances may not be exactly the ‘‘square-root formula’’ but the formula is a good representation of the orders of magnitude of transport reduction and corresponding ecological improvement. In addition, the local farm producers are often very small one family or other democratic firms, which also save jobs and create a more interesting and creative type of work. We have referred in several contexts to the inefficiency of the capitalist system with respect to transportation over long distances and the corresponding overuse of polluting fuels. One of these was the case of the alternative of offspring firms of cooperative and democratic firms. But this is only a minor portion of our argument about destructive trade. By destructive trade, we understand a double destruction; one of jobs in the United States, and second the ecological destruction of the environment through the wasteful use of energy in transportation over long distances, such as importing from China trillions of dollars of goods that could have been produced in the United States. But there is a hidden inefficiency and destruction – similar to the mental destruction through high pressure advertising/pushing – namely the destruction of scientific minds that prefer a theory of superiority of free trade, which is false and which is accepted by capitalist economists because it serves the capitalist leaders who benefit from free trade while hurting the workers and the rest of the population. The fallacy of the free trade argument is explained in a short paper included as an Appendix to this chapter. The destructive trade analysis and a corresponding discussion of remedial solutions can be found in my less known study published by the Tinbergen Institute in India. (‘‘Destructive International Trade from Justice for Labour to Global Strategy,’’ International Journal of Development Planning Literature, 13(1), 1998).

Related to this discussion and also relying on the analysis of the appendix is perhaps the most powerful argument to be introduced here in concluding our discussion: Relying on the erroneous theory of free trade – or using the lying thereof – in the United States and perhaps other developed countries, we have moved most of our manufacturing capacities to countries like China. Thereby we have stimulated if not originated the superdevelopment of that country, which now is becoming the dominant polluter of the planet. And thus for the 30 pieces of capitalist profit – here and in China – we have sold down the drain the welfare and happiness of millions of working families in the United States. In addition we have strengthened the forces of ecological destruction in the whole world.
APPENDIX: REVISION OF THE THEORY OF COMPARATIVE ADVANTAGE AND EXPLANATION OF THE 2008 WORLD CRISIS I will be very brief because there is a lot to say and my arguments are of considerable relevance for understanding and analyzing the present world economic crisis. For easy reference, I number my paragraphs. 1. In the great depression, many countries tried to improve their condition through the so-called beggar-thy-neighbor policy, which failed in its intention and made things worse for all. 2. Formal economic theory was developed to explain #1 above in the form of the theory of comparative advantage, showing that free international trade is optimal in the sense that world income and output will be maximized. 3. In its simplest form/model of two countries and two factors of production, the theory is associated with the names of Heckscher and Ohlin [H-O] and is based on the following assumptions. 4. Fixed supplies of labor (giving one dimension of a box diagram). 5. Fixed supply of capital (giving the second dimension of the box diagram). 6. International immobility of capital. 7. International immobility of labor. 8. Full employment of labor. 9. Full employment of capital. 10. Production functions subject to constant returns to scale, identical throughout the world, smooth, and differentiable.

11. For a wide variety of – but not all – conditions the theory based on these assumptions just stated, free trade will lead to factor price equalization among countries. 12. Using the conclusion of factor price equalization and all the underlying assumptions, the H-O theory can be generalized for a large number of factors, products and countries into the Heckscher–Ohlin–Vanek theory. 13. For a theoretical representation to hold or to be useful in understanding world economic phenomena – and to support the present day free-trade policy – it is desirable that the assumptions and conclusions used or derived would correspond to observed real conditions and observations. 14. From the point of view of observable reality, all the assumptions of the theory – except #7 are incorrect. Thus a priori the theory must be rejected. 15. And thus the liberal free trade policies of today’s world and the tenets of the World Trade Organization must be rejected and questioned. 16. The theory and its recommendations may have been at least partially valid in the context of the great depression, where the conditions of factor price equalization may have been approximated among the advanced economies involved at that time. 17. However the ‘‘signature’’ of the theory, factor price equalization, is patently untrue and unrealized in the present-day situation where wages between rich and poor countries can reach one thousand percent and beyond, in a world where for practical purposes the supply of labor in the low wage part of the world is infinite (quoting the Bible, ‘‘the poor will always be with us’’). The ‘‘thousand percent’’ differential is fundamentally exogenous to the trading system, not determined by the factor price equalization theorems. 18. Under such conditions, the original theory of comparative advantage must be replaced with a much truer and better theory that I refer to as the theory of destructive trade. That theory leads to the conclusions that under free international trade and mobility of capital and immobility of labor, the capital owners will gain a lot, especially in the United States, imports of transportable goods will increase and labor employment and labor incomes in the United States will decline, especially in the import competing sectors: precisely the tendencies observed in the United States. The standard claim that free trade will be beneficial to the world economy is by no means guaranteed. The only definite conclusion is that the world distribution of income, especially in the United States, will favor capital. The destructive trade theory is nothing but a simple application of the Second-Best theory where certain exogenous variables do not correspond to optimal solutions.

19. While I have produced the formal demonstration of a barter solution (similar to that used for the H-O theory) elsewhere, the simple version thereof can be summed up – representing the rich part of the world by the United States and the poor part by all the underdeveloped and developing poor world – the Less Developed Countries – as follows. 20. Why should anything that is transportable (TG ¼ transportable goods) in the long run be produced, under free trade and mobility of capital, with one thousand percent wage differentials, in the United States and not in the LDCs? 21. The forces of destructive trade implied by #20 are precisely what have been prevailing in the world over the recent decades. 22. The forces of reduction of production of the TGs and reduction of employment of labor was mitigated by Mr. Greenspan’s ‘‘cover-up ‘‘ by virtually zero real interest rates and overexpansion of not transportable goods, especially housing construction, Macdonald’s and consumer credit. 23. Neglecting Tinbergen’s principles of matching policy instruments and objectives, relying only on credit and interest rates, not using other policy tools, assisted by greedy users and developers of toxic debt instruments, the situation had to explode ultimately in the subprime crisis in which we are living now. 24. The crisis is far more serious than the Obama advisors are suggesting, because through the explosion we have ‘‘killed’’ the economy of the not transportable goods while still experiencing the ‘‘killing’’ of the transportable goods in the United States through the latent force of Destructive Trade. 25. It seems to me that half-cooked policies and strategies will not suffice in curing the economy. Perhaps the predicted December 2009 unemployment of 8.1% reached in February 2009 can give us some insight.
GENERAL CONCLUSION The theory of comparative advantage as applied to real-world phenomena – and the practical free-trade recommendations must be rejected or at least questioned. The more realistic, even if less elegant mathematically, theory of Destructive Trade should be a better guide in defining world trade solutions and leading us in the long run out of the present global crisis.
THE CASE FOR CAPITALISM: A COMMENT ON JAROSLAV VANEK’S ‘‘CAPITALISM, ECONOMIC DEMOCRACY, AND ECOLOGICAL DESTRUCTION OF OUR PLANET’’ Jed DeVaro and Adrian Stoian Jaroslav Vanek argues that the ecological degradation of the planet is more severe in a capitalist system than it would be in a fully democratic one. At the heart of the ecological preservation question is how the classic public goods problem can be solved, and we are skeptical that a fully democratic system could solve this problem any better than the capitalist system, particularly given that consumer demand for environmental protection appears to be income elastic and that the capitalist system can be expected to generate higher levels of societal wealth than the democratic system. While we disagree with Vanek’s conclusion and with many of its underlying arguments, we agree that the ecological well-being of the planet is of great importance, that it is expected that economic activity will have ecological implications, and, therefore, that it is well worth comparing the expected ecological impacts of alternative socio-economic systems.

Vanek highlights the desirability of family-owned firms and small geographic distances between the locations of production and consumption. He argues that such an arrangement helps to internalize externalities such as pollution, since the members of a family-owned firm, living near the point of production, have a greater incentive to protect the environment from negative production externalities (e.g., pollution) than do shareholders, most of whom are dispersed over a wide geographic area and will not live near the externality-heavy point of production. Thus, the democratic system is less likely than the capitalist system to produce output levels exceeding the social optimum. We think that local production tends to be higher-cost, more resourceintensive production, which is unlikely to be good for the planet. Scale economies allow for more efficient production using fewer resources, so in this sense capitalism might be better for the environment than a system based on localized production. Furthermore, Vanek’s argument applies to local pollutants but not to global ones. For example, because carbon emissions do not cause their harm locally, local owners would not care about such emissions any more than dispersed owners. Even in the case of local pollutants, the local inhabitants need not be owners to exert at least some influence on a firm’s decisions regarding production and the externality. A capitalist firm, after all, must hire workers to produce. Many of these workers will live near the point of production, and they have tastes for clean air and water just like the owners in a democratic system. They also choose where to live and where to work. Given fairly reasonable assumptions on information, worker mobility, and competition in the labor market, capitalist firms in a free market have an incentive to recognize the preferences of workers, since these preferences affect the firm’s costs. In equilibrium, a compensating differential will emerge in which workers living near the production point will demand higher wages. Given that economies of scale are likely to arise in pollution abatement, the capitalist firm may mitigate the negative externality to lessen the need for ongoing higher wages. One might worry that the capitalist firm might give undue attention to short term profits, neglecting the long term, but with proper delineation and enforcement of property rights the capitalist firm can be expected to bear the future costs of its decisions. Vanek further argues that in a democratic system labor would enjoy higher real wages and levels of well-being than in a capitalist system. His argument suggests that the family-owned firm is insulated from competitive pressures in its effort to maximize its family’s well-being. But the familyowned firm must sell its product in a market where consumers demand

lower prices, so it is not obvious how the family-owned enterprise can indulge a taste for ecological protection any more than a capitalist firm. Furthermore, the members of a family-owned firm care not just about ecological protection but also about eating and consuming goods, so ‘‘maximizing the family’s wellbeing’’ does not mean exclusively focusing on ecological effects. The notion that capitalist societies are only about profits, consumption, and materialism contradicts some basic observations. Consider the fact that countries around the world with essentially capitalist systems have developed national parks to protect habitat, and there have been many successful campaigns targeted at preserving endangered species and providing other public goods. The wealthier a society becomes, the more it can afford to allocate its resources to enhance and protect the environment. Furthermore, innovation and entrepreneurship drive technological improvements that can make transportation cheaper and ‘‘greener’’ over time. We do not see why consumer well-being would be higher in the system Vanek proposes than in a capitalist one, and we should add that any discussion of well-being must account for the prices consumers must pay for goods and services. Vanek further argues that transportation costs and the concomitant environmental degradation are higher in a capitalist system than in a democratic system. While this argument seems plausible, if we narrowly focus on transportation costs, we lose sight of some larger tradeoffs. We already mentioned efficiencies arising from economies of scale. In addition, capitalism facilitates innovation and entrepreneurship, which in turn spur economic growth. One must ask what the prospects are for innovation if a system based on family-oriented sole proprietorships replaces the capitalist one. Our fear is that the rate of innovation would suffer. Innovation requires an efficient capital market, and an infrastructure, which naturally implies some agglomeration to achieve critical mass.1 The innovative ideas needed to advance in science and other areas of human endeavor require the synergies that are sparked when human and capital resources are concentrated. Vanek’s recommendations of decentralization and saving on transportation costs are at odds with this. We struggle to conceive of a Silicon Valley taking root in the type of system Vanek proposes. And we cannot resist feeling that it was not by accident that the Industrial Revolution was born in Britain rather than China. While we believe that the decentralization Vanek advocates may stifle innovation and entrepreneurship in general, in some industrial sectors the case for decentralization might appear stronger. For example, in agriculture the use of pesticides on large acreage and genetically modified seeds may
302
JED DEVARO AND ADRIAN STOIAN
have adverse health effects, and the quality of produce deteriorates when it is transported over large distances. However, there is no guarantee that small farmers will use fewer pesticides than large farmers.2 Furthermore, transportation costs from farms to grocery stores appear to be less significant than energy costs associated with storage and food preparation, which are in turn likely higher in a decentralized system due to inefficiencies in household consumption of food; there is also a cost advantage to largescale agricultural production. As a consequence, the decentralized approach is likely to imply higher prices and, due to less transportation, fewer options, both of which will hurt consumers.3 At the same time, as consumers become wealthier, their demand for products like local, organic fruits and vegetables and free-range, grass-fed beef increases, that is, demand for these goods (as for pollution abatement) is income elastic. A shift toward a more decentralized approach to agriculture could occur in the context of a capitalist system, as evidenced by a growing number of farmers markets and community-supported agricultural and organic grocery stores and restaurants that feature local produce. Wealth in capitalist societies has increased to the point that, for example, consumer attention increasingly turns to the conditions under which chickens and cows live before being slaughtered for food. These are high-income-elasticity issues that would not have occupied the minds of the typical 18th-century consumer, and our feeling is that issues such as California’s 2008 ‘‘Proposition 2’’ resonate with voters precisely because of the capitalist system and the wealth it creates, rather than despite it.4 Shifts from centralized to decentralized production, motivated on ecological grounds, must be driven by consumer demand, and the higher average incomes in a capitalist system can be expected to facilitate that. Vanek emphasizes that the location of production matters for the global ecological footprint. We argue that from a global perspective and over a longer term, it should not matter whether the pollution emanates from China or from the United States. In the short run global pollution might increase when production moves from a developed economy like the United States to a developing one like China, in part because the poor in developing economies have weaker preferences for environmental quality than do the rich in developed countries. However, given that demand for environmental quality is income elastic, over time the increasing wealth in developing countries can be expected to lead to increased demand for environmental protection. While this may take a long time, in the shorter run there is another mitigating factor.5 Those (richer) consumers in developed countries will tend to prefer environmentally friendly production practices. So the innovative capitalist firm can be expected to devise ever more efficient ways
The Case for Capitalism

to produce in environmentally friendly fashion and to appropriately inform consumers, reaping a markup through product differentiation. The consumer information assumptions required for this argument to hold are increasingly reasonable in the age of the Internet. Vanek also comments on the distributional consequences of trade for domestic labor, although its relevance to his main theme of ecological degradation should be clarified. Obviously trade has distributional consequences, and in the United States in recent decades the wages of low-skilled labor in some sectors have been pressured by trade. At the same time, trade intensifies demand for U.S. exports which creates new demand for domestic labor.6 We also note that the wages paid to domestic labor are only one side of the coin; on the other side are the prices these workers face for the products they consume. All consumers welcome the lower product prices facilitated by trade, including those family members who would work in Vanek’s family-owned firms (and who care about eating and consuming as well as about ecological degradation). Vanek’s arguments create the impression that the democratic firm is somehow insulated from competition. But how would such firms compete with cheaper imports? What is the likelihood that they would have fared better than their capitalist counterparts once Deng Xiao Ping started the process of reform in China?7 From an American standpoint, it seems fortunate that American companies had the scale and the backing of capital markets to quickly deploy resources to China for investment and to seize the new opportunities in that part of the world. Finally, if we take a global perspective when looking at the wages of low-skilled labor, rather than focusing narrowly on the U.S. experience, we must balance the pressure on the real wage of U.S. laborers against the tens of millions who escaped poverty in developing countries including China. This is cause for celebration for opponents of global wage inequality. Vanek also argues that profit maximization is not desirable because labor costs and use tend to be minimized. In 1900, half of the labor force in the United States worked in agriculture, versus less than 4 percent today. Labor productivity in agriculture has increased dramatically during the last century. But imagine telling people in 1900 that in less than a century there would be less than 4 percent of the workforce in agriculture. This would likely have incited fears that the U.S. economy would be paralyzed with an unemployment rate approaching 50 percent, due to minimization of labor costs. But such fears ignore the role that innovation and technological improvements in a capitalist system play in expanding the set of opportunities. We believe that Vanek’s proposed system is less likely than capitalism to generate these benefits and that a better way forward is to foster an environment of creativity

and entrepreneurship, while supporting people’s acquisition of the skills needed to succeed in a highly technological, innovative and globalized 21stcentury economy. We see no evidence suggesting that product quality will be worse in a capitalist system than in a democratic one. The capitalist system produces cars such as BMW that many in the world dream of owning, yet the Trabant (the East German car of choice until its production was discontinued after the crumbling of the Berlin Wall) was, it is fair to say, somewhat less appealing than a BMW. Product quality is driven by consumer preferences; if there is a demand for quality in the capitalist system, the capitalist firm will provide it. Furthermore, if what consumers prefer is a lower-quality, cheaper product, then how is anyone better off if what is provided is a higher-quality, more expensive product? The demand for high-quality products, like the earlier demands we have noted, is income elastic. We would expect that the wealth generated by a capitalist system will lead to increasing demands for product quality, but quality must be driven by consumer demand y not the other way around. Vanek argues that the welfare-maximizing democratic firm can control its working hours to a greater extent than the profit-maximizing capitalist firm, thereby producing less, using fewer resources, and causing less environmental degradation. He further argues that workers in the democratic system can consume more leisure, since ‘‘labor incomes per hour can be higher than the capitalist wage.’’ These arguments neglect several points. First, workers with varying tastes for work versus leisure and for workplace conditions can select among employers, so that competing profit-maximizing employers must recognize the preferences of workers. Employers choosing to ‘‘set’’ hours without regard to worker preferences will meet an unhappy fate in a competitive environment. Second, Vanek focuses on wages but ignores product prices. His language suggests that market competition only drives down wages and not product prices. Consumers care not about what wage they are paid but rather about what that wage can buy for them. Finally, the notion that workers in a democratic system can be expected to ‘‘consume more leisure’’ might well be true, if we interpret leisure as involuntary unemployment. By stifling innovation, entrepreneurship, and the resulting growth that creates jobs, the democratic system can be expected to have a depressive effect on employment.8 To conclude, we are skeptical that a fully democratic system would be better than a capitalist system at fostering the ecological welfare of the planet and enhancing human welfare. The fully democratic system with its family-owned firms and restricted trade seems unlikely to encourage global
305

cooperation on issues like climate change. We believe a capitalist system is more likely than the alternative to generate the greatest amount of societal wealth and that as a society’s wealth increases so does the strength of its preferences favoring ecological protection. To be clear, we are not arguing that economic activity has no negative consequences for the environment or that these consequences are not serious and cause for potential concern and possible government intervention.9 We are merely arguing that Vanek’s alternative, to us, is not obviously better on the ecological front, and is clearly worse on other fronts. That being said, we end where we began, by reiterating that the broad point Vanek raises – that is, that alternative economic systems may have differential ecological effects on the planet – is important and worthy of dispassionate and reasoned debate.
NOTES 1. This agglomeration often results in the formation of cities that are more energy efficient than decentralized spatial organizations. 2. For example large farmers can afford to invest in sophisticated technology like satellite imaging that facilitates a more efficient use of inputs, including pesticides and – importantly in many regions – water. 3. As an example illustrating limited choice, consider that the cost to Oklahoma of producing its own Pinot noir would be prohibitively high. 4. Proposition 2 (Standards for Confining Farm Animals) was on the November 4, 2008, ballot in California and passed with 63.5 percent of the vote. The proposition created a new state law – which goes into full effect on January 1, 2015 – prohibiting the confinement of farm animals in a manner that does not allow them to turn around freely, lie down, stand up, and fully extend their limbs. The proposition marked the first time that California voters were called upon to vote on such a question. 5. The process is likely to take a longer time in countries where institutions are weak, and the relationship between income and environmental protection might be non-monotonic. Furthermore, even looking within countries, there could be considerable variation across different types of pollution in the speed with which environmental protections are implemented. In the long run, however, the prospects for global environmental protection should improve as countries become wealthier. 6. This is true even for American products produced abroad. In recent years, some American companies have increased sales of their products in China. Even though production of these goods is often finalized in China, the growing sales in China create demand for American labor since a substantial share of the total labor costs is associated with countries other than China, including the United States. 7. Increases in competition naturally lead some to argue for protectionism. However, our sense is that autarkic economies have fared worse than open ones, ceteris paribus. By any measure, China today is more open than China few decades

or centuries ago, and the consequences of this for its rate of economic growth are clear. 8. Also on the subject of leisure, we note that labor-saving home appliances such as washing machines and microwaves allow consumers to spend more time on recreational activities. These products too are the result of innovation and entrepreneurship, which again are fostered by capitalism. 9. Such intervention would be of the usual form – for example, Pigovian taxes and subsidies, tradable emissions permits, or World Trade Organization regulations concerning production practices – and might have a role in both the capitalist and fully democratic systems.
REJOINDER Jaroslav Vanek I welcome any dialogue on the present subject because it clarifies and makes us reflect on such a significant issue of our times. Especially I would like to stress the subject of the appendix on destructive trade. We live in a world impregnated with the notion of free trade optimality, but in many contexts the notion is incorrect, and such mistakes can be serious for the advanced economies including the United States. For the theoretical mind of economists, let me stress that the theory of optimal comparative advantage includes the conditions of full employment and factor price equalization [or near-equalization], but with wage differentials of the order of one thousand percent the optimality is most unlikely. The unemployment and the financial crisis of the great recession are the most dramatic and convincing verification – as well as substantiation of my arguments concerning global ecology.
